TV channel frequencies dvb t2. How many channels does a digital set-top box of the DVB-T2 standard show and which channels are broadcast free of charge on digital terrestrial television?
TV), it's time to move on to the most important part - setting up digital television. How to set up digital television with your own hands? Read more about this.
I will show using the example of a receiver Mystery MMP-71DT2, and like me, his software is completely identical to Rolson. If you have a different console, the principle will be the same, but you may have to look at the instructions.
How to connect everything
First, let's connect antenna to the receiver, and the receiver to the TV. Preferably through, so the image quality will be as clear as possible. If there is none, then through ordinary “tulips”, they usually come complete with the console. Look at the connectors in the instructions, you will get something like this. If the antenna has an amplifier, first turn it off, then you can always turn it on.
We launch all this equipment, set-top box, antenna, TV. Select the desired video input. If everything is done correctly, you will see a start menu like this:
How to set up digital television through “auto search”
By default, the set-top box is not configured for anything, and you yourself will need to catch the channels that are broadcast in your region. The easiest way is to run an auto search.
After launching the auto search, the set-top box will think for a long time, and should find something in the end. Important: since each one is transmitted at the same frequency, you will catch channels not one at a time, but in packs of ten at once. So be patient. If in analog TV channels are caught one at a time, then a few minutes may pass, and the set-top box will search. But then all 10-20 channels will pop up immediately.
After the search is over, the set-top box will prompt you to add the found channels. If you find all 20 pieces, congratulations, the process is complete!

How to check signal quality when setting up digital TV
Check that the signal is strong enough and everything is set up well.
It's very easy to do. You should have an INFO button on your set-top box; pressing it three times displays data on the quality and intensity of the signal. Look in the instructions, it may be called differently, but it will do the same thing:
The higher the signal, the better. Optimal - from 60% onwards
If both indicators are high, above 60%, everything is fine.
Check on both multiplexes, say, on Channel One and TNT.
Since different multiplexes are transmitted, you can catch the first one well, and the second one poorly, or vice versa. Your task is to rotate the antenna so that both are caught well.
But in practice it happens a little differently. For example, you can catch duplicates. When identical channels will occupy several places at once. It doesn't seem critical, but it's annoying. How to treat, I.
What to do if you caught duplicates or didn’t catch anything
The second option is when not everything was caught, or nothing was caught. Fine tuning and manual mode will help us here. We read about it. However, if you live in a city and there are towers near you, then in 90% of cases an auto search is enough for you.
To sum it up
As you can see, setting up dvb t2 digital television with your own hands is not a difficult task. And you certainly shouldn’t call a specialist who will do the same thing for you for a thousand rubles)
A package of channels broadcast on the same frequency is called multiplex. The number of channels in one multiplex can be from 1 to 10. The composition and number of channels is determined by the broadcaster, for example, the state.
There are now 3 multiplexes operating in Crimea so that they do not interfere with each other, as in analogue broadcasting, in each region broadcasting is carried out on different frequencies (CHANNELS).
DVB-T2 broadcasting in Russia, Ukraine and a number of other countries is carried out only in the decimeter frequency range - these are from 21 to 69 UHF (UHF) channels.
List of transmitters and frequency channels broadcasting in Crimea

Foros - 21, 43, 44 (Cape Sarych)
Yalta – 26, 35, 37 (Yuzhnoberezhnoye Highway 55)
To receive DVB-T2 you need (preferably) an external decimeter television antenna without an amplifier with modern cable with minimal signal attenuation in it. It is possible to use all-wave antennas. More often the antenna with good cable Receives a signal better than an antenna with an amplifier and an old cable. The use of the Soviet cable RK-75 is not allowed; such a cable was not designed to receive signals in the UHF range, so it has high signal attenuation.
It also happens that in the same locality, for example, Nikolaevka, Zuya, depending on the place of reception, reception can be carried out from different directions. So, on one side of the lowland in Zuya, the signal can only be received from Simferopol, and on the other side of the settlement only from Belogorsk.
If reception is carried out outside the line of sight of the direction to the transmitter, then maximum signal possible even in the opposite direction from the transmitter. In this case, the reflected signal is received. To determine the ideal orientation of the receiving antenna, select the manual channel search mode on your TV or set-top box, then enter one of the channels (preferably with a lower number from the list above) from the transmitter from which you want to receive the signal. Now you can see the scale of the received signal level and orient the antenna according to it.
Rotate the antenna 5-10° in any direction, count to 10 in your head, and write down the signal strength. Rotate the antenna another 5-10° in the same direction
(further) and again count to 10 and record the level of the received signal. Thus, rotate the antenna a full 360° around its axis.
After this, you will see from your recordings from which direction the maximum signal is coming.
With the advent of the era of digital terrestrial television, many subscribers of cable and satellite networks began to increasingly think about connecting free broadcasting . Indeed, according to the Federal Target Program on the development of a digital broadcasting network, in open access will appear more than twenty television channels V excellent quality absolutely free. Which includes mandatory federal television channels.
The question arises - how to connect digital terrestrial television at home?
There's nothing complicated about it. To receive digital terrestrial television you will need any standard subscriber equipment DVB-T2/MPEG-4 with mode support Multiple PLP and UHF antenna ( DMV) range. The antenna can be either collective (installed on the house, also called a common antenna) or individual, installed directly in your house or apartment. Depending on the distance to the transmitting center, you must select the desired antenna. They are divided into active (with an amplifier) and passive. When purchasing an antenna, you can first check the power of the transmitting equipment installed in your region and the distance to the transmitting center. Based on the data obtained, select an antenna.
Approximate coverage radius of transmitting stations:
10 W– about 3 km;
50 W– about 5 km;
100 W– about 15 km;
500 W– about 25 km;
1 kW– about 30-35 km;
2 kW– about 35-40 km;
5 kW– about 40 – 50 km.
Let's move directly to the reception equipment. Three main groups can be distinguished: televisions with a built-in DVB-T2 tuner, set-top boxes of the same standard and digital computer tuners DVB-T2. Their settings are similar, if not the same.
Video: how to set up DVB-T2 digital terrestrial television
Connect digital broadcast box It’s best to follow the manufacturer’s instructions; it’s almost impossible to make a mistake there. Also, you can look official video from RTRS:
A few recommendations, also from RTRS:
connect the antenna cable plug and, if necessary, the digital set-top box to the TV;
connect auto channel search - the TV will tune to the corresponding digital broadcast channel, when tuning to channel in manual mode it is necessary to indicate the channel frequency (for example, 35 TV channel, 685 MHz);
Most digital TVs (and set-top boxes) have a built-in signal level and quality indicator, which will allow you to optimally configure your antenna to receive a digital terrestrial signal (see the operating instructions for the TV).
On TVs with a built-in DVB-T2 tuner, all manipulations are carried out through the TV menu. There shouldn't be any difficulties there either.
We recommend updating the software of your subscriber equipment to the most current one. This can be done in specialized services, or yourself (if you are confident in your abilities). The software can usually be downloaded from the manufacturer's official websites.

When a new level of data transmission quality appeared, it was launched digital network television DVB-T2. Digital television gives high quality pictures and excellent transmission signal. But to set up a connection to this network, you need to have the necessary knowledge, choose the right receiver and configure it well.
How to connect the T2 module and configure it will be described below.
How to connect a T2 set-top box to a TV
The T2 tuner is quite easy to connect to your TV. If you have experience connecting players, antennas and other devices to your TV, then connecting the receiver will not be difficult.
We connect the antenna to the receiver, and from it we connect the wires to the TV. This can be done using standard HDMI, tulip or SCART cables. The most important thing is that you don’t have to pay to call a specialist. However, if the master can connect the set-top box to the TV for free, then it’s worth leaving the matter to him.
How to connect DVB-T2 to a TV without a set-top box
To connect your TV directly to the DVB-T2 network without purchasing a receiver, you can immediately purchase a TV with a built-in DVB-T2 tuner. This saves space, time and costs. Among other things, you can control T2 channels with one TV remote control, while the receiver will have two remote controls.
Today, almost all LCD TVs have a built-in tuner, which makes connection easier. Simply insert the antenna into the desired socket.
How to set up DVB-T2 using a receiver
After installing and connecting the receiver, you need to set up the television. To do this, follow simple steps:
- We go to the console menu.
- Click “Quick setup”.
- If the default is another country, then set it to “Russia”.
- Then you must select the “DVB T2” standard. It often appears in the DVB T/DVB T2 standard field, which leads to the receiver looking for DVB T quality channels, and only then DVB T2. We need DVB T2 and its excellent quality.
- Then click “Auto Configuration” and everything will be done automatically.
- After finding the channels, you can also watch detailed information by connection quality by clicking the “Info” button.
This way you can set the receiver to receive all the right channels. But the setup does not always go smoothly. Sometimes problems arise.
What to do if DVB T2 setup does not occur
There are several options why the setup does not occur:
- The problem is in the receiver;
- The problem is in the antenna;
- The problem is with the TV.
First, try setting up using a different antenna. If it helps, then the problem is in the antenna, and if not, then the receiver is to blame.
If the antenna is to blame, then only a specialist can help. If the receiver, then several options are possible. Firstly, the receiver may have incorrect firmware. Then you need to reflash the console. To do this, go to the manufacturer’s website, download the new firmware, write it to a flash drive and insert it into the receiver. It will update itself and the problem will be fixed.
If updating the firmware does not help, then the problem is most likely in the electronics. In this case, it is better to return the set-top box for service or replace it under warranty.
You can also check the TV itself. To do this, use the set-top box on another TV, and if it works, then the problem may be in the TV settings. In this case, you should contact the manufacturer. There they will be able to tell you how to correctly set the TV settings to connect the receiver.
How to choose a set-top box for DVB-T2
The choice among receivers is quite large. Here are the most popular receivers that are recommended to buy:
- Trimax TR-2012HD
- Strong SRT-8500
- Strong SRT-8502
- Thomson THT702
- Trimax TR-2012HD PVR (TR-2013HD PVR)
Their price starts from 1000 rubles and above, depending on the functions. More expensive receivers have more fine-tuning options, better signal reception, more various inputs to connect additional devices, and they also work faster. Compared to satellite set-top boxes, the DVB-T2 receiver is inexpensive.
You can also go to any hardware store and there, on the spot, choose new receiver, after consulting with a specialist.
Introduction of terrestrial digital television on the territory of Ukraine DVB-T standard 2 allowed to significantly expand the zones confident reception signal from TV towers, compared to analog signal. Also, the ease of setup and installation of T2 did their job, they became much more popular satellite television with MFA channels.
Let's move on to the practical side and talk about the direct installation of all the equipment necessary to receive DVB-T2. Many modern televisions are already equipped with an integrated DVB-T2 receiver, in this case it is enough to find out the position of the repeater, point the antenna at it and scan the available channels using the TV. In the case of simple TV, installation and connection of T2 occurs somewhat differently, we will discuss it now. To install T2 in the standard version you will need:
- Digital DVB-T2 receiver
, the form factor you need, for example for hidden installation with a remote IR sensor, etc. The choice is now huge, there is practically no significant difference, everyone can choose for their needs. Practice shows that it is worth purchasing from a reliable store with a guarantee; we suggest you buy a receiver from our partners who will provide you service, warranty and repair.
Buy MINI DVB-T2 digital set-top box with delivery from China
- UHF antenna , in practice, so-called “Polish antennas” are often used, you can also purchase an antenna manufactured by Konvalia, Margoon, etc., you just have to take into account that the antenna must be taken with a gain margin, since you can predict how the signal will be received in specific case hard to say. It is also desirable that it contains an amplification board that can receive power from both external unit nutrition.
- Cable, regular TV , almost any will do, but it’s better to take one with a braid filling percentage of 50% or more.
- RCA or HDMI cable for connecting the receiver to the TV , may be included or must be purchased separately.
Connecting digital T2 using the example of the World-Vision T38 receiver
First you need to install the antenna, if it has not been installed before. It’s probably stupid to advise anything here, I’ll just say that follow the manufacturer’s recommendations, and at least first turn it in the required direction. You can find out which direction to point the antenna by looking at neighboring antennas or calculate the direction, for example, using Google or Yandex maps.
Connecting a T2 digital receiver to an antenna will also not cause much difficulty; the manufacturer and standardization make this process simple and it’s quite difficult to make a mistake.
When connecting, it is difficult to confuse something, the RCA cable is easy to connect, you just need to follow the color on the plug and socket, yellow to yellow, white to white, red to red. The antenna connector also will not allow you to connect other plugs to it; in this receiver model it is located on the left edge. It is also possible to connect via HDMI, everything is simple here, the COAX connector is used to connect a digital audio amplifier and is practically not used in standard configurations.
After all the cords are in place, we connect the last one - the power supply connector, for this model it is located on the side panel.
At this point, the connection of the T2 receiver is almost complete. Next, you need to turn on the TV and receiver. By pressing the “AV-TV” switch button on the TV remote control, we switch from the antenna socket to the “tulips”; on newer TVs, we select the input to which the receiver is connected. The following should appear on the screen:
The receiver will restart and a menu will appear with searching for channels and setting the initial parameters of the receiver:
We select the parameters and click “Auto search”, the receiver will scan and display the found channels.
If not all channels are found or there are none at all, adjust the antenna and repeat the search from the receiver menu until the number of channels and reception quality satisfy you. Enjoy watching!
To set up equipment to receive a DVB-T2 signal, specialists are usually invited. But any technically literate man can do this on his own. To do this, you need to know the frequencies of DVB-T2 digital channels.
Digital terrestrial television (DTTV) is special technology transmission of image and sound through digital signal coding using digital channels. The main difference between digital encoding and analog is that digital provides signal delivery with minimal losses. In this case, the video image and sound are protected from exposure to any external factors(interference).
Another important advantage of a digital signal is the increase bandwidth channels when receiving data. Digital data can be compressed, making it possible to transmit large number television channels in best quality and with additional information(subtitles, soundtracks). CETV technologies include interactivity (the ability feedback with the audience). The TV audience can not only view content, but also participate in surveys, vote for someone in some competitions, etc.
The transition to CETV is being carried out in many countries around the world. Residents of the most remote and sparsely populated villages and hamlets, who previously had the opportunity to watch only 1-2 channels, can now receive 15 or more channels in good quality on their televisions.
Digital terrestrial radio and television stations are launched in the latest European standard DVB-T2. This is being done as part of a general project to transition from analogue to digital broadcasting. In the CIS countries (Russia, Kazakhstan and others) this is done under a special government order.
The main advantages of using digital modular radio television stations of the DVB-T2 standard:
- increasing the stability of signal transmission and recording paths to various types of interference;
- reduction of transmitter power;
- an increase in the number of TV programs broadcast in the same range;
- improving picture and sound quality on TVs;
- creation of TV systems with new image standards (high-definition television);
- development of interactive TV systems;
- archive and recording of TV programs;
- transmission of additional information in the TB signal.
For private entrepreneurs who want to engage in pay multi-program television, the service of construction of turnkey digital terrestrial television transceiver stations is available. Technical capabilities one station medium power allow you to broadcast a signal over a distance of 20-50 km, i.e. The coverage area includes a city with a population of 50-100 thousand people. This good option commercial solution for small operators cable television, because there is no need for complex and expensive work on laying cables to the subscriber’s apartment.
When connecting DTTV, subscribers have access to more than 20 free channels, including mandatory federal channels.
Settings
To receive DTTV, any subscriber equipment of the DVB-T2/MPEG-4 standard that supports the “Multiple PLP” mode and includes a UHF antenna is required. The antenna can be either collective or individual. Antennas come in different types and different power, they are selected depending on the distance to the transmitter.
Approximate coverage radius of transmitting stations:
- 10 W – 3 km;
- 50 W – 5 km;
- 100 BT – 15 km;
- 500 W – 25 km;
- 1 kW – 30-35 km;
- 2 kW – 40 km;
- 5 kW – 40-50 km.
Equipment for signal reception can be divided into 3 types:
- TVs with a built-in DVB-T2 tuner;
- TVs and separate set-top boxes (receivers) of the DVB-T2 standard;
- computer tuners of the same standard.
Setting up any of the equipment options is not much different from the others. You can invite a specialist to set it up, or you can do it yourself by studying the instructions on the Internet.
- Connect the antenna cable plug and the set-top box to the TV.
- Start auto-search for channels - the TV itself will tune to the corresponding digital terrestrial channel. If you configure manually, you will need to specify the frequency of DVB-T2 digital television (for example, 35 TB, 685 Hz).
- Most TVs and set-top boxes have a built-in signal level and quality indicator. This makes it possible to optimally tune the antenna. On those TVs that have a built-in DVB-T2 tuner, all actions are performed through the TV menu.
It is recommended to update the software of the subscriber equipment to the most current one. This can be done either in services, or at home, if you invite a specialist. The software can be downloaded from the manufacturer's official website.
With the advent of the era of digital terrestrial television, many subscribers of cable and satellite networks began to increasingly think about connecting free broadcasting. Indeed, according to the Federal Target Program on the development of a digital broadcasting network, more than twenty television channels in excellent quality absolutely free. Which includes mandatory federal television channels.

After the advent of digital television, many users wanted to switch to its reception. It's not just about frequent discussions and the desire to try something new. The signal quality is an order of magnitude higher, and ease of access increases attractiveness. It is also possible to connect digital TV to outdated kinescope models using additional devices, and to modern televisions.
Methods for receiving a digital signal
There are several ways to connect a high-quality signal to your TV:
- Cable television. Reception is carried out via a common cable. The disadvantage is subscription fee and not universal availability;
- Satellite TV. The signal is transmitted via satellites, and received using an individual dish. A subscription fee plus the purchase of special equipment is also required;
- Terrestrial television. The digital TV signal is distributed from terrestrial repeaters and can be received from an indoor or outdoor antenna. This is absolutely free method watching TV shows in a modern format. It has disadvantages: the signal level is often low, the picture quality can be affected by the weather, the location of the tower, etc.
The least expensive method is to receive digital television through an antenna installed and configured by the user.
How digital television works
The transmission of pictures and sound for digital television is accomplished by encoding the video signal and sound over digital channels. Digital coding differs from analogue in its immunity to interference (external obstacles). Blurred, fuzzy picture, stripes are impossible here. The image is either clear or completely absent.
If the reception is uncertain, then perhaps the picture will disintegrate into squares, disappear from time to time and reappear. It depends on how you set up the antenna. Alternatively, you can install a different antenna or raise and deploy the existing one, pointing it at the TV tower.
Required equipment for viewing
- Antenna;
- A separate set-top box with a DVB T2 tuner that supports the MPEG 4 standard and can operate in Multiple PLP mode.
You can use a regular analog antenna. If the TV was released relatively recently, it may have a built-in tuner required format(the legacy DVB T format is no longer supported). Then you don't need to buy anything else.
To find out whether there is a built-in DVB T2 tuner, you can look at the data in the data sheet. It’s even easier to find a TV model on the Internet and get a comprehensive answer.
Selecting a digital tuner
At first glance everything set-top boxes are the same. The main thing is not to make mistakes in the main technical specifications. But there are other features that affect the further operation of the equipment and the breadth of functions covered:
- The lack of buttons on the external panel of the set-top box will require you to use it only using the remote control, which is not always convenient;
- If the tuner does not have a USB port, this technique cannot be used as a media player. If available, you can record TV shows and play back photos and videos.
Important! A good choice is a set-top box with a separate power supply. Usually it is built inside. The most common cause of tuner failure is a faulty power supply. If it breaks, you need to repair or replace the entire set-top box, and the remote power supply must be replaced separately without any problems.
Many people hang the TV on the wall, and quite high. Then it is inconvenient to use the usual console design. There are equipment modifications - compact set-top boxes that are attached to the back of the TV with tape. The strength of the fastening needs to be considered. Such a receiver is controlled by a remote control through a separate sensor attached to the same tape on the external panel of the TV. Power is supplied via a wire from the TV's USB port.
The set-top box can also be used in conjunction with a computer monitor (if there is an HDMI port). Then you can watch digital television from a regular antenna. If the built-in television tuner fails, it can be easily replaced using the receiver.
What channels are available for viewing?
To watch free digital channels via regular antenna The 2017 list contains two multiplexes:
- first RTRS 1 – frequency 546 MHz, channel 30;
- second RTRS 2 – frequency 498 MHz, channel 24.
Technical data is valid for Moscow and the region. They may differ in other regions. A total of twenty television channels and 3 more radio programs are available.
Important! The TV does not receive additional channels. Antenna settings will not affect the number of received channels, but only their quality.
How to locate a TV tower
Users living in the city, in the signal reception area from the TV tower, are not puzzled by such questions. But for residents of remote towns and villages, the information is relevant. What knowledge is needed for best choice And correct settings antennas:
- The exact location of the tower and the distance to it;
- Technical parameters (channels and broadcast frequencies), using which you can catch digital signal in this area. This is necessary so that the user can configure TV channels on the set-top box manually;
- Is the entire list of channels available for reception? There may be one or two packages.
Full information about TV towers is on the official RTRS website. There are maps where you need to search bar enter the name of a specific locality. A map of the given area will immediately open, on which all transmitting television towers are indicated (green - operating, black - under construction). If you click on the cursor hovered over the selected village, information will be available about where and how many kilometers away operating transmitters are installed, channel numbers (TVCs), broadcast frequency, number of packages).
The active menu includes a function that allows you to find out the coverage areas of individual repeaters.
Now, armed with knowledge, you need to determine whether it is enough to install an indoor antenna or whether you will need an outdoor, more powerful one.
Antenna types
The analog signal is received by the MV antenna. DVB Antennas are more compact. There are combined samples capable of receiving both ranges. From such a combined design, you can remove unnecessary elements, and you will get an excellent UHF antenna. For example, if long whiskers (an element for the MV signal) are present, they can be removed.
All antennas are divided into:
- active;
- passive.
Active are those whose devices use amplifiers. The antenna with amplifier must be connected to a power source. If a receiver is used, 5-volt power for the amplifier is supplied through it. This is done in the menu settings. The option is called “Antenna Power”.
Amplifier does not always mean best reception, in some cases its use will even do harm:
- In an area near a TV tower, turning on the amplifier may lead to a complete loss of reception due to the signal being too strong;
- The amplifier is the weakest element of the antenna and often fails. Plus a power supply and additional wires, which also require repairs and replacements;
- The intensity of the TV signal itself is provided by the design of the antenna. And the amplifier simultaneously increases the level of noise and interference;
- If you want to connect another TV to a passive antenna, this is easier to do.
Passive designs do not have additional amplification and are usually used in areas with a stable signal.
Antenna selection and installation
An old antenna may be suitable for receiving a digital signal if it consists of short elements or a combination. If you have working, serviceable antennas, all that remains is to find out whether they will effectively catch “digital” in local conditions.
The UHF signal does not have a wide coverage area. Therefore, to distribute it, it is necessary to build a network of transmitters. The quality of the signal is greatly influenced by the surrounding landscape, the presence of high-rise buildings, mountains, forests, and the power of the repeater. Antenna installation must take into account all these factors.
Reliable reception area
A zone of stable and reliable signal is considered to be an area within a radius of no more than 10 km from TV tower. Here's a simple one indoor antenna copes well with the reception. If you have an amplifier, you don't have to use it.
If the signal disappears, the image is torn, then you need to connect the existing amplifier through the set-top box by using the corresponding menu item. Power will be supplied via the antenna cable.
Multi-storey buildings can become a problem due to the reflection of decimeter waves. But this same reflection can be used. Let's say the antenna does not receive reception when it is oriented towards the TV tower. Direct it at nearby tall buildings; reception of the reflected signal may be much more effective.
It is necessary to check the presence of electrical appliances (third-party power supplies, etc.) near the indoor antenna, as well as metal blinds on the windows. They can significantly weaken the signal.
Short circuit
There are times when the set-top box suddenly stops responding to the use of the remote control or buttons, the image and sound disappear, and “Antenna short” is displayed on the screen. The problem does not mean that digital television is not working. There is simply a short circuit in antenna cable or in the receiving device itself.
Why did the short circuit happen? There may be several reasons:
- The presence of a short circuit in the cable due to careless installation, most likely at the connection points. The antenna plug can only be damaged due to a manufacturing defect;
- Active at work receiving device, power is supplied to the amplifier. The amplifier is sensitive to lightning and can be damaged during bad weather;
- The passive antenna is connected, and the amplifier power is turned on in the receiver menu. Passive devices are often short-circuited.
In the latter case, you need to disconnect the receiver from the network, separate the antenna from it, then apply power again, on the connected tuner in the menu settings, set “Antenna power” to the “Off” position.
Important! Finding and eliminating causes short circuit is performed after disconnecting the set-top box from the power supply.
Area remote from the TV tower
Far distance is considered to be more than 30 kilometers from the repeater. If there is a powerful transmitter and line of sight, we install a small receiving device such as a wave channel or log-periodic. You need to point the antenna at the TV tower. In such conditions, it is even possible to use a room device with an amplifier.
With increasing distance and when a populated area is located in low places, the requirements for the antenna increase. More powerful samples are needed. A good receiving device must include an amplifier, and its boom is long enough. There are examples with several arrows, but they will only be needed under extremely bad conditions.
Many users have the Polish antenna, as in the recent past it was popular due to its affordable cost. Another name for it is lattice. Can this design be adapted for digital television?
It is quite functional, but a number of changes are required. The antenna amplifier does not contribute, but interferes with signal reception. Therefore, he must be taken out of work. Simply unplugging the power supply is often ineffective. It’s more reliable to remove it from the amplifier board tv cable and connect it there to the two upper bolts: to one - the central core, to the other - the shielding braid. Thus, the amplifier is excluded from the circuit, and the antenna becomes passive.
Antenna and TV setup
There are several ways to properly configure a digital signal. The choice depends on the reception conditions.
Auto search
This method is the simplest, but it requires a strong, stable signal. The equipment is installed, turned on, in the settings menu you select digital channels, and auto search is activated. TV in automatic mode finds and saves the entire list of channels.
Manual mode
Let's say the TV cannot catch anything in auto search mode. Or channels with interference were found. These images are not digital. Perhaps the TV went through the entire frequency range and caught several analog channels.
Now it will be useful to know the numbers of TV channels (TVCs) through which the signal is transmitted for each multiplex. Information about the location of the television broadcaster will also be useful for pointing the antenna in the right direction. If the house is surrounded by other residential buildings, you can navigate by neighboring reception devices, but not by satellite dishes who “look” at their companion.
- In the menu you need to enter manual setting, having previously selected DTV (digital television);
- Enter the channel number or its frequency by dialing from the remote control;
- At the bottom of the menu, two indicators will appear showing the intensity TV signal and its quality. Sometimes there is one indicator;
- If even a slight signal is present, you can begin to rotate and move the antenna to achieve its amplification. You should not expect an instant reaction when changing the position of the receiving device. It will appear in a few seconds. The search must be carried out step by step, with pauses. When the antenna is external, it is difficult to do this alone; it is better to take an assistant;
- Immediately after the appearance of a stable signal from good level you can start searching for channels and saving;
- The channels of the second multiplex are configured in the same way, if its reception is technically possible in the given area.
Important! If the signal disappears, then appears again with the scale filled to 100%, and so on one by one, this means there is no reception.
Complete lack of signal reception
This situation is typical for particularly unfavorable conditions, in low places, closed by mountains, near high-rise buildings, with low-power towers located far away.
Searching for a television signal must be done manually. At the same time, to initially display it on indicators, you need to show patience and endurance, having tried different methods:
- Purchase a powerful active antenna;
- If there are other towers nearby, you can sometimes try manual searching on a TV set to alternative repeaters. Perhaps the signal conditions will be better;
- Raising the antenna to a height using a mast gives a good effect;
- When the TV tower is located close, and the house is located in the center of a densely built-up area with high-rise buildings, you should not rush to buy an expensive, powerful receiving device. It is better to experiment with the reflected signal, alternately pointing the antenna at different sides on neighboring buildings or place it on the roof.
Setup via receiver
Old TVs, models without built-in tuners with DVB T2 support require configuration through the receiver.
CRT TVs are connected to a digital set-top box using tulip cables (RCA), LCD models are connected to an HDMI cable. In the first case, when setting up, the AV mode is selected, in the second - HDMI. The mode is selected from the television remote control. On remote controls, the mode selection is located under different buttons: INPUT, SOURCE, VIDEO, just a rectangle with an arrow.
Subsequent configuration is performed using auto search or manual using the add-on remote control. The antenna must be connected to the set-top box.
Receiving a digital television signal with a regular antenna is an easy way to ensure yourself viewing a high-quality picture, requiring minimal financial costs and physical effort. With the development of the network of television towers, signal reception conditions will improve.
