Homemade indoor dvb t2 antenna. How to supply power to an active antenna amplifier. The most powerful antenna for DVB-T2

). Thus, an antenna is a kind of transmitter (receiver). In this article we will understand what antenna is needed for receiving DVB-T2 signal.

Antenna types:

By type, antennas can be divided into indoor, outdoor and long-distance antennas. We are interested in antennas that capable receive standard signal DVB-T2. They can be divided into two groups: indoor and outdoor. In turn, they are divided into active and passive.

The digital terrestrial television signal of the DVB-T2 standard is transmitted in decimeter ( UHF) range. This range (UHF) is within 470–862 MHz. In Russia, these frequencies fill the channels from 21st to 69th television channel (TVK) inclusive.

We would like to immediately make a reservation that there are no special antennas for DVB-T2 reception, all these are ordinary decimeter antennas with or without a signal amplifier. Choose An antenna for DVB-T2 reception will not be difficult. There are two main criteria to consider here: distance to the transmitter and relief terrain. Two services will help us with this:

Next, we proceed directly to the selection of a DVB-T2 UHF antenna. If the terrain of your area is more or less flat and the distance to the transmitter is no more than ten kilometers, then a regular UHF antenna without an amplifier will suit you. Although, if the price difference is not big, then we recommend purchasing an active antenna (with an amplifier), because you can always turn it off.

Indoor DVB-T2 antennas:

As an example of a passive indoor DVB-T2 antenna, let's take the Sirius 2.0 antenna, manufactured by REMO. You can read it on our website.

As an example of an active indoor DVB-T2 antenna, let’s take the “MINI DIGITAL” antenna, from the same manufacturer “REMO”. You can also find it on our website.

Outdoor DVB-T2 antennas:

Outdoor antennas are also classified into active and passive. They must be used when the distance from the transmitter is more than 10 kilometers. It is recommended that these antennas be pointed accurately at the transmitting station.

As an example of an outdoor DVB-T2 antenna, let's take the SELENA MINI antenna, manufactured by REMO.

As an example of an outdoor active DVB-T2 antenna, let’s take an antenna made by REMO.

Outdoor DVB-T2 antennas for long-distance reception:

If the distance to the transmitting equipment is over 30 kilometers, then you will need highly directional antennas with increased sensitivity. These antennas can receive signals at a distance of up to 100 kilometers. Also do not forget that such antennas must be installed on an appropriate height.

As an example of an outdoor active DVB-T2 antenna for long-distance reception, let’s take an antenna made by REMO.

Since the advent of radio communications, the issue of using an antenna has been very relevant. In 1961, engineer Kharchenko proposed a design consisting of two rhombuses. With its help, he caught American broadcasts.

Evolution

The antenna, invented by Kharchenko, is double square made of thick copper wire. The squares are connected to each other with open corners, and in this place they are connected. To improve directionality, a grille made of conductive material is installed at the rear.

Perimeter of each square equal to length wave to which the reception is tuned. The diameter of the wire for 1-5 television channels should be about 12 cm. Because of this, for radio communications and meter range television (1-12 channels) it turns out to be very cumbersome. To facilitate the design, a gasket with three wires of a smaller cross-section was used, but it still had a lot of weight and dimensions.

Second life zigzag antenna, created by Kharchenko, received when it appeared broadcasting in the UHF range. Everyone remembers rhombuses, circles, triangles and other homemade figures as a TV antenna for receiving decimeter waves, which hung on many people’s balconies and outside their windows. They were one of the signs of that time.

In 2001, Professor Trevor Marshall (USA) proposed using this design in Bluetooth and WiFi networks.

This article talks about what devices are available for these purposes and how to make such an antenna with your own hands.

You can use one zigzag antenna drawing for all bands. The only differences are in size.

Antennas for TV

There is practically no meter-wave television, and Kharchenko’s zigzag antenna was not used to receive these channels due to its large dimensions. Therefore, this article only talks about its application for UHF and DVB-T2.

Improving UHF reception

For UHF reception, the zigzag antenna has the following dimensions:

• L1 (outer side of the square) – 141.8 mm;
• L2 ( inner side square) – 135.6 mm;
• L3 (frame length) – 397.4 mm;
• L4 (frame width) – 198.7 mm;
• L5 (connection gap) – 8.4 mm;
• D (height of racks) – 65 mm;
• B (screen width) – 565 mm;
• H (screen length) – 565 mm;
• wire diameter – 9.6 mm;
• quantity of wire – 1166.9 mm.

It turns out to be quite broadband and does not require additional settings. Connects with a piece TV cable. Characteristic impedance - about 50 Ohms. The antenna matches well with coaxial cable with resistance of both 50 and 75 Ohms. To improve broadband, it can be made not from wire, but from copper or aluminum strip and connected with rivets. The copper strip can be additionally soldered. The length of the strip is calculated between the rivet holes.

If you use antenna amplifier, then the second square is not needed, you can take only one.

Improved T2 reception

Digital TV DVB-T2 is broadcast at UHF frequencies on channels 21-69 using the multiplex method. Therefore, the design for T2 needs the same dimensions as the antenna for digital television DCV range. However modern televisions if the signal is too strong, it is blocked. Therefore, if the transmitter for T2 is too close, and you want to use the old frame for DVB-T2, then you may need a weaker amplifier for digital television, you will have to cut off one square or remove the screen from reverse side. You can also make such a device for t2 with your own hands or use a digital TV antenna made in the form of a circle, 555 mm long. This is enough for digital TV.

Designs for the Internet, 3g and mobile communications

For mobile communications, Bluetooth, 3g and WiFi use such short waves and high frequencies that the entire device is about 10 cm long and is manufactured according to the same drawing for all ranges. The only differences are in the sizes, which can be calculated using an online calculator. You can also use it for your mobile phone.

DIY zigzag antenna

Making an antenna yourself is not difficult. For production you need:

• single-core copper wire;
• soldering iron;
• pliers;
• ruler;
• coaxial cable with wave impedance 50 Ohm;
• conductive material for the screen (foil getinaks, DVD or CD disc, sprat can, etc.);
• a stand that provides the correct distance between the antenna and the screen, for example, a plastic bottle cap;
• glue.

The manufacturing process can be divided into several stages:

1. Clean the wire from insulation;
2. Using a ruler, mark the folds;
3. Use pliers to bend the wire in the previously marked places. The more accurately the markings were made and the wire was bent, the better the reception will be;
4. The cable connection points are tinned;
5. The cable is tinned, or a plug is put on the cable, to which pieces of wire 10-15 mm long are soldered;
6. The wire is soldered to the antenna;
7. A stand and a screen are sequentially placed on the cable;
8. The entire structure is glued, for example, with silicone.

Improved WiFi and Bluetooth reception

WiFi is transmitted like other types wireless communication, radio waves. Therefore, to improve the performance of a WiFi router or other devices, you can also use this design. According to reviews, if you use a parabolic plate as a screen (alternatively, you can bend it out of a tin can), the gain reaches 31 dB. When using a homemade reflector, its curvature is selected experimentally. To do this, on the device to which the signal is transmitted, you need to install a program that shows the signal level and, changing the curvature of the screen, monitor it.

The calculation is made at a frequency of 2445 MHz.

• L1 (outer side of the square) – 30.8 mm;
• L2 (inner side of the square) – 29.6 mm;
• L3 (frame length) – 84 mm;
• L4 (frame width) – 43 mm;
• L5 (connection gap) – 1.9 mm;
• D (height of racks) – 13.6 mm;
• B (screen width) – 122 mm;
• H (screen length) – 122 mm;
• wire diameter – 2.5 mm;
• quantity of wire – 256.6mm.

Important! The more accurately the dimensions are maintained, the better the reception will be.

You can use a piece of foil getinax for printed circuit boards as a screen. For mechanical strength, the screen is soldered to the wire braid.

You can use a CD or DVD disc. The disk has a thin layer of foil on which information is recorded. In this case, you can make an antenna in a CD box.

Install the Kharchenko antenna horizontally. This is due to the polarization of the signal.

Bluetooth uses the same frequencies as WiFi. Therefore, you need a WiFi range antenna of the same size.

Connecting to a router

If the router has a connector for connecting external antenna, then a plug is soldered to the end of the cable and inserted into the connector.

If it is not there, then to connect you need to open the modem and solder the cable to the board. The shorter the wire, the better. The power of the router is small, and losses in the cable are sometimes decisive.

Attention! This work can only be performed by experienced specialists. Opening the device will void the warranty.

Connecting to a laptop

IN WiFi laptops built-in boards for mobility and reduced size. Therefore, there is no external antenna, and the internal one is low-power. To connect to it, you need to disassemble the laptop and know exactly where it is located. But there is alternative option With using USB WiFi adapter with antenna. Having cut it, you can find the central core and screen. A coaxial cable is respectively soldered to them. Ideal option will be installed directly on the adapter in order to reduce cable losses.

Improved 3g reception

Modern mobile Internet uses the 3g standard with a signal frequency of 2100 MHz and a wavelength of 143 mm. Therefore, the dimensions will be as follows:

• L1 (outer side of the square) – 37.1 mm;
• L2 (inner side of the square) – 35.5 mm;
• L3 (frame length) – 104 mm;
• L4 (frame width) – 52 mm;
• L5 (connection gap) – 2.2 mm;
• D (height of racks) – 17 mm;
• B (screen width) – 148 mm;
• H (screen length) – 148 mm;
• wire diameter – 2.5 mm;
• quantity of wire – 305.4 mm.

Structurally, the 3g antenna is no different from the design for WiFi.

Connecting to a 3g modem

The most effective way is to connect the cable inside the router, but to do this you need to be a specialist in the field of repairing mobile communication equipment. For everyone else, we can suggest another method.

Wireless connection

To do this, cut two pieces of copper or brass foil, 45 and 27 mm wide and long enough to wrap the modem and solder the edges. We do the same with a wide section, solder the central core of the cable to it and put it on the modem. Instead of a wide piece of foil, you can strip 15-20 cm of wire and wrap the modem tightly. A narrow piece is bent in a semicircle and soldered to the cable braid. The relative position for best reception.

Additional information. If the antenna is connected directly to the modem, without a cable, and the modem itself is connected using a USB extension cable, then losses in the cable can be avoided.

Connect to a smartphone or tablet

It is necessary to strip a piece of cable and wrap the central conductor 10-15 turns around the phone. You can also take a piece of brass or copper foil, solder the central core of the cable to it and insert it between back cover and a cover.

Improved 4g reception

Mobile Internet of the 4g standard uses a frequency of 2600 MHz with a wavelength of 115 mm. Therefore, the dimensions will be:

• L1 (outer side of the square) – 28.9 mm;
• L2 (inner side of the square) – 27.6 mm;
• L3 (frame length) – 81 mm;
• L4 (frame width) – 40.5 mm;
• L5 (connection gap) – 1.7 mm;
• D (height of racks) – 13.2 mm;
• B (screen width) – 115 mm;
• H (screen length) – 115 mm;
• wire diameter – 2 mm;
• quantity of wire – 237.9 mm.

Cell phone antenna

Mobile communications operate in two bands. You can find out which one you need on your operator’s website.

Comparative characteristics

"Double" Bi-Quad (double biquad)

Double biquadrat is also a Kharchenko antenna. It is made with your own hands in the same way as a regular biquadrat. It differs from a regular biquadrat in that at the vertices of the squares, instead of the corners, there are additional squares. The dimensions of these squares are exactly the same as the main ones. Therefore, no additional calculation is needed; you can take the calculation for a regular biquadrat. The calculation for the Kharchenko antenna can be found in this article or use the online calculator program for the calculation. The wires at the intersection are insulated from each other.

The double biquadrat can be continued in the same way. Those who want to make it can easily calculate the length of the wire. This gives additional gain.

Digital television is broadcast in the UHF range. Therefore, you can use almost any UHF antenna. But I needed simple, easily repeatable and strong UHF antenna range.
Such that you could carry it with you, and on occasion you wouldn’t mind giving it to people for a small amount.

The basis was taken from the famous “ eight“, with the difference that I used it without a reflector.
The material for the antenna sheet can be any conductive material of suitable cross-section. It can be copper or aluminum wire with a thickness of 1 to 5 mm, a tube, strip, busbar, corner, profile... I took copper wire with a diameter of 3 mm. Easy to solder, easy to bend during assembly, easy to straighten if bent.
The outer side of the square is 14 cm, the inner side is slightly smaller - 13 cm due to the fact that the middle of the two squares does not converge, about 2 cm from corner to corner.

So, if you are making an antenna not from wire, then measure it this way - the top sides are 14 cm, the sides are 13.

All sizes are approximate. Don't be afraid to get shortchanged or make mistakes. Our plans do not include making an antenna that meets all standards. We need a simple but workhorse. A surrogate, but reliable. Surrogate because:
1 . Personally, I definitely couldn’t keep the sizes.
2 . There is no reflector.
3 . I took a 50 ohm cable instead of 75 ohm, but with a thick braid. Friends usually used this cable for car antennas for 27 MHz radio stations.
Nevertheless, the antenna works quite well.

A digital signal has a peculiarity; it either exists or it doesn’t. Upon admission analogue television, different channels were shown with different levels of interference, and when removed, the level of snow on the screen simply increased until the signal completely disappeared. In digital, the signal is almost the same on all channels and if there is reception, then there is all channels.
I have tested this antenna on more than a dozen TVs in our region.

So. We measure a piece with a total length of 112 cm and bend the wire. The first section is 13 cm + 1 cm for the loop (for strength). The second and third are 14 cm each, the fourth and heels are 13 cm each, the sixth and seventh are 14 cm each, and the last eighth is 13 cm + 1 cm stiffening loop.

We strip 1.5 - 2 cm at both ends, twist the two loops behind each other, and then solder the joint. This will be one cable connection pin. After 2 cm another. It doesn’t matter where to solder the central core or the braid.

Solder spacing 2 cm

I took about three meters of cable. In most cases, it’s enough if you don’t do it for yourself personally. For yourself, measure out as much as you need.

I stripped the cable from the antenna side by two centimeters, to the plug - 1 cm. If the plug is like in the photo. You can take any, stronger.

Stripping the cable

The plug was cleaned with a file and a scalpel.

After sealing, both soldering points are filled with glue from a gun. On the plug, first hot glue is poured into the soldering area and into the plastic cap, with a reserve; the excess can then be removed. Then, before the glue cools down, everything quickly comes together. You can’t gnaw such a joint with your teeth. Reliable and at the same time flexible.

The soldering on the antenna itself is also filled with glue, but for the rigidity of the structure, a frame is taken - any lid, box, .... I took the cap from a 20-liter water bottle, of which I had accumulated a sufficient amount. If you are making an antenna like me for mass production, then it is better to immediately use common materials that are literally lying under your feet for better repeatability of the antenna. If the antenna is made in a single copy for quick riveting, then you don’t have to fill anything at all.

The result is such a design that can be stuck anywhere - on a cornice, on a curtain, on a window frame. To do this, you can carry with you a piece of wire, a couple of screws, a couple of pins...

Antenna assembly

If the antenna is dented during transfer, it can be easily and without damage aligned. This is perhaps its main advantage.
I don’t always carry this design with me, but only when I receive a specific order to connect a DVB-T2 digital television tuner. It fits easily with the tool in my backpack.

It is more convenient to make several antennas at once. Takes less time.

This is how my friend fixed the antenna, using it as an outdoor one. The tower is about 9 km away. Reception is reliable despite the simplicity of the antenna.

The era of digital signals has arrived. All broadcast television companies began to work in a new format. Analog TVs are reaching their end. They are still in working order and are found in almost every family.

So that old models successfully complete their resource, and people can use them when viewing digital broadcasting, just connect the DVB-T set-top box to the TV receiver and pick up the TV wave signals with a special antenna.

Any home craftsman can not buy an antenna in a store, but make it with his own hands from available materials for watching digital TV programs at home or in the country. The two most accessible designs are described in this article.

A little theory

Operating principle of an antenna for digital packet television

Any television signal propagates in space from the emitters of the transmitting television tower to the TV antenna by an electromagnetic wave of a sinusoidal shape with high frequency, measured in megahertz.

When an electromagnetic wave passes through the surface of the receiving beams of the antenna, a voltage V is induced in it. Each half-wave of a sinusoid forms a potential difference with its own sign.

Under the influence of an induced voltage applied to a closed receiving circuit of the input signal with resistance R, electric current. It is amplified and processed by the digital TV circuit and output to the screen and speakers as image and sound.

For analog models of TV receivers, an intermediate link works between the antenna and the TV - DVB-T set-top box, performing decoding digital information electromagnetic wave into normal form.

Vertical and horizontal polarization of digital TV signal

IN television broadcasting According to state standards, electromagnetic waves are emitted in only two planes:

1. horizontal.

In this way, transmitters send emitting signals.

And users simply need to rotate the receiving antenna in the desired plane to maximize the power potential.

Requirements for a digital packet television antenna

TV transmitters distribute their signal waves to short distances, limited by the line of sight from the top point of the TV tower emitter. Their range rarely exceeds 60 km.

For such distances, it is enough to provide a small power of the emitted TV signal. But, the strength of the electromagnetic wave at the end of the coverage area should form a normal voltage level at the receiving end.

A small potential difference, measured in fractions of a volt, is induced at the antenna. It creates currents with small amplitudes. This imposes high technical requirements on the installation and quality of manufacture of all device parts. digital reception.

The antenna design should be:

• manufactured carefully, with a good degree of accuracy, eliminating losses electrical power signal;
• directed strictly along the axis of the electromagnetic wave coming from the transmitting center;
• oriented according to the type of polarization;
• protected from extraneous interference signals of the same frequency coming from any sources: generators, radio transmitters, electric motors and other similar devices.

How to find out the initial data for calculating an antenna

The main parameter influencing the quality of the received digital signal, as can be seen from the explanatory first figure, is the length of the electromagnetic wave of radiation. Under it, symmetrical arms of vibrators of various shapes are created, and the overall dimensions of the antenna are determined.

The wavelength λ in centimeters can be easily calculated using a simplified formula: λ=300/F. It is enough just to find the frequency of the received signal F in megahertz.

To do this, we will use a Google search and ask it for a list of regional TV communication points for our area.

As an example, a fragment of a data table for the Vitebsk region is shown with the transmitting center in Ushachi highlighted in red.

Its wave frequency is 626 megahertz, and its polarization type is horizontal. This data is quite sufficient.

We carry out the calculation: 300/626=0.48 m. This is the length of the electromagnetic wave for the antenna being created.

We divide it in half and get 24 cm - the desired half-wave length.

The tension reaches its maximum value in the middle of this section - 12 cm. It is also called amplitude. The whip antenna is made to this size. It is usually expressed by the formula λ/4, where λ is the electromagnetic wavelength.

The simplest TV antenna for digital television

It will require a piece of coaxial cable with a characteristic impedance of 75 Ohms and a plug for connecting the antenna. I managed to find a ready-made two-meter piece in the old stock.

I cut off the outer shell from the free end with a regular knife. I take the length with a small margin: when setting up, it’s always easier to bite off a small piece.

Then I remove the shielding layer from this section of the cable.

The work is finished. All that remains is to insert the plug socket into the connector on the TV signal set-top box and direct the bare wire of the inner core across the incoming electromagnetic wave, taking into account horizontal polarization.

The antenna should be placed directly on the windowsill or secured to the glass, for example, with a piece of tape, or tied to the blinds mount. Reflected signals and interference can be shielded with a strip of foil located a short distance from the central core.

Such a design can be done in literally ten minutes and does not require any special material costs. It's worth trying. But she is capable of working in the zone confident reception signal. My building is screened by a mountain and a multi-story building. The transmitting television tower is located at a distance of 25 km. Under these conditions, the digital electromagnetic wave is reflected many times and is poorly received. I had to look for another technical solution.

And for you on the topic of this design, I suggest you watch the video of the owner of Edokoff “How to make an antenna for digital TV”

Kharchenko antenna at 626 MHz

To receive analogue television signals of various wave frequencies, a zigzag design previously worked well for me. broadband antenna, which do not require complex manufacturing.

I immediately remembered one of their effective varieties - the Kharchenko antenna. I decided to use its design for digital reception. I made the vibrators from a flat copper bar, but it’s quite possible to get by with round wire. This will make it easier to bend and straighten the ends.

How to determine the dimensions of a specific antenna

Online calculator

Let's use the all-knowing Google search. We write to command line: “Calculation of the Kharchenko antenna” and press Enter.

We choose any site you like and perform online calculations. I went into the first one that opened. This is what he calculated for me.

I presented all his data with a picture indicating the size of the Kharchenko antenna.

Manufacturing of antenna design parts

I took the information provided as a basis, but did not accurately maintain all the dimensions. I know from previous practice that the antenna works well in the broadband wavelength range. Therefore, the dimensions of the parts were simply slightly increased. The half-wave of each harmonic of the sine wave of the electromagnetic TV signal will fit into the arm of each vibrator and will be received by it.

Based on the selected data, I made blanks for the antenna.

Vibrator design features

The connection of the ends of the figure eight busbar is created in the center at the bending stage. I soldered them with a soldering iron.

I created it according to the “Moment” principle, made it with my own hands from old transformers, and has been working for two decades. I even soldered 2.5 square copper wire with it in thirty-degree frost. Works with transistors and microcircuits without burning them out.

In the near future I plan to describe its design in a separate article on the website for those who also want to make it themselves. Follow publications, subscribe to notifications.

Connecting the antenna cable to the vibrator

I simply soldered the copper core and braid to the figure eight metal with different sides at its center.

The cable was tied to a copper bar, bent into a loop in the shape of a semi-square vibrator. This method matches the resistance of the cable and antenna.

Screening grid design

In fact, the Kharchenko antenna often works normally without signal shielding, but I decided to show its manufacture. For the base I took a wooden block. I did not paint or varnish: the structure will be used indoors.

In the back side of the block I drilled holes for attaching the screen wires and inserted them, and then wedged them.

The result was a screen for the Kharchenko antenna. In principle, it can be made of a different design: cut from a piece of frontal armor of a tank or cut from food foil - it will work approximately the same.

On the back side of the bar I secured the vibrator structure with a cable.

The antenna is ready. All that remains is to install it on a window to work in vertical polarization.

When a television receiver is located at a great distance from the transmitting generator, the power of its signal gradually weakens. It can be increased with special electronic devices- amplifiers.

You just need to clearly see the difference between the signals received by the antenna, which can be:

1. simply weakened;
2. contain high-frequency interference that distorts the shape of the digital sinusoid into the shape of some kind of “doodleball”.

In both cases, the amplifier will fulfill its role and increase the power. Moreover, the TV will clearly perceive and display a weakened signal, but with an amplified signal, playback problems will arise.

The waves are designed to eliminate such interference:

• high-pressure filters;
• screens.

They must be measured with an oscilloscope, and the methods of application of various designs must be analyzed in each specific case individually. The antenna is not to blame here.

The purpose of television antennas has long been known to everyone - these are devices designed to receive and transmit digital or analog signals to TV equipment. Traditionally, antennas are divided into three types: indoor, outdoor and hybrid, combining features of both types at the same time.

Initially, when television broadcasting was just beginning to develop, and televisions did not have such multifaceted functionality, the quality of the signal (especially at a considerable distance from the source) left much to be desired. Passive antennas, serving only as a receiver, could not provide pictures and sound of appropriate quality, which left a strong imprint on the popularization of media technology and television broadcasting in general. It was then that antennas began to be equipped with special amplifiers that greatly increased the quality of the signal entering the TV receiver.

Today, a huge number of companies around the world are developing antennas, but not all of them meet domestic data transmission standards and requirements for perceived frequency ranges. As a purchase recommendation, we have selected seven of the best TV antennas in three main categories that received the highest ratings from consumers.

The selection of devices was made taking into account:

1. Technical specifications
2. Customer reviews
3. Antenna cost (price-quality ratio)
4. Opinions of electronics market experts
5. User voting results

The best indoor antennas for digital television

Indoor antennas operate in the UHF or meter range, receiving signals at a distance of up to 30 km. Such devices have some limitations on the quality of television waves, and require careful configuration. However, they are compact, inexpensive and can be moved anywhere without special problems. The leader in the indoor digital television antenna market is considered to be the manufacturer Remo.

5 Remo Inter 2.0

Best desktop antenna
Country: Russia
Average price: 870 rub.
Rating (2018): 4.5

The top four best indoor antennas for digital television are closed by Remo Inter 2.0. The device has a fairly affordable price, while possessing good functionality, which makes it one of the best on the market. The receiver is capable of working with 20 digital, 10 analog and 3 radio signals, unlike competitors that work only with digital. Convenient control antenna will allow you to set the required level of signal amplification and achieve maximum quality.

Among the strengths of this device In reviews, buyers highlight the low cost, excellent design and ease of installation. The antenna housing itself is collapsible, but can be assembled literally in no time. Separately, it should be said about the power and antenna cables - they not only have high-quality insulation, but also the same length, thanks to which the device can be installed in the right place. TO weaknesses This is attributed to not always stable signal reception and low-quality plastic housing.

4 RA-A30

A good indoor antenna with balanced characteristics
Country: China
Average price: 990 rub.
Rating (2018): 4.6

One of the typical representatives of Chinese indoor digital signal reception antennas, showing good results in the picture stability component. Despite the poor-looking “pin”, which strongly resembles the antennas of standard portable tape recorders, the reception quality remains the same high level. The reason for this is a good standard amplifier (with a coefficient of about 28-30 decibels), closed in a sealed plastic case.

As for the aesthetic component, consumers, in general, are satisfied with the external data of the RA-A30, noting only the strong soiling of the front panel. The reliability parameters here are not the most optimal, but for stable operation it is quite enough for several (and with proper care – 5-7) years. Thus, this antenna is an excellent option for those who are looking for an inexpensive solution for the home coupled with good performance parameters.

3 Hyundai H-TAI320

Excellent adaptability to customization of structural elements
Country:
Average price: 680 rub.
Rating (2018): 4.8

Interesting specimen home antenna for analog and digital television, showing generally similar results with models like HARPER ADVB-2120. The closed circuit of the original shape is combined here with two “horn” antennas (articulated with the body), which provides extensive customization options for normal signal reception. By the way, the Hyundai H-TAI320 is capable of operating both in the VHF frequency range (87.5-230 MHz) and in the UHF range (470-862 MHz), and with a sufficient degree of picture quality.

Good quality is achieved, first of all, due to the presence of a built-in amplifier, the gain of which is a good 30 dB. It is possible to receive digital signals in DVB-T and DVB-T2 formats, as well as FM and DAB. The key advantage of the Hyundai H-TAI320 can be considered the ratio of cost to quality. Having identical performance indicators to competitors, this model has a disproportionately large tuning radius of receiving elements, which is especially important in conditions of concentrated interference.

2 HARPER ADVB-2120

Optimal price-quality ratio
Country: China
Average price: 570 rub.
Rating (2018): 4.8

The second place in the ranking of the best indoor digital television broadcasting antennas goes to the HARPER ADVB-2120. This model has a whole range of optimal characteristics, supported by a huge number of complementary reviews from domestic consumers. Wide range of picked up frequencies (from 87.5 to 862 MHz) and the ability to amplify not only digital, but also analog channels(FM, VHF and UHF) enters into a pleasant “synthesis” with original design, thanks to which the antenna can fit into any interior. It is also important that the signal amplifier is powered directly from the receiver or TV, since it does not have an external network adapter. This imposes some restrictions on the use of the antenna (since not all models of digital equipment support the possibility of direct power supply), but has a positive effect on its compactness.

The ergonomic characteristics of the HARPER ADVB-2120 are also excellent: the antenna can be easily placed on a plane if there is sufficient free space.

How to choose a good antenna

The choice of television antennas, like many other devices, is accompanied by some nuances that should be discussed in advance. We strongly recommend that you pay attention to the following parameters:

Antenna type. Depending on the place of application, antennas are divided into indoor, outdoor and hybrid, which can be placed in both conditions. If the received signal is sufficiently stable and reliable, you can get by with a simple indoor antenna. Otherwise, you should give preference to hybrid or full-fledged street options.

Antenna range. IN in this case antennas are divided into two types: broadband and narrowband. The first option is advisable to use when the frequency of television broadcasting is unknown in advance. This option is suitable for thrifty owners, in case new channels appear on television. Narrowband antennas are oriented to a specific frequency and it is impossible to adjust them to other bands without losing the current one.

Signal amplification. This function is inherent exclusively in active antennas, the design of which provides for the presence additional module. This design option is suitable when the received signal requires amplification to generate a clear and high-quality image on the TV screen.

Directivity of antennas. A simple and unpretentious way to improve signal quality by shifting the radiation pattern allows antennas to provide focused reception only at a strictly defined azimuth. This effect allows you to avoid interference caused by the reflection of various signals from the walls of residential buildings and other “initiating” objects.

Antenna internal resistance. It is very important that this parameter matches the resistance of the cable connected to the device. The standard resistance of equipment for receiving a television signal is 75 Ohms, and for a radio signal - 50 Ohms.

Design. The aesthetic side of the issue when buying a television antenna should also not be left aside. Often, a pleasant appearance indirectly affects the improvement of the quality of the signal used, since the correct geometry and rational arrangement of additional elements are reflected in the physical parameters.
