Do-it-yourself antenna subduing the TV signal is easy. Selecting a pіdsilyuvacha antenna for a TV set or a combination with a hand. Stronger cable TV

Systems of cable and broadcast televisiy movement are being developed everywhere with skin rock. However, unimportantly on the growl of growth, and the expansion of the possibilities of television equipment, the brightness of the image on the TV screen is low. It is important that the reception of the TV-signal of the antenna lie down in the form of various officials: correct installation, design and form of fittings, up to the repeater. Help raise the quality of the possessed image autonomous subsidy otherwise, the replacement of the priymach is a larger straining device. At whom we look around, as if we were able to strengthen the weak, unstable signal of the TV antenna.

First of all, there are radio technical innovations, it is necessary to analyze why the receiver’s functioning is low. The reasons for the shift and the filthy brightness of the image can be:

• Significantly in the distance of the life of the repeater;
• wrong;
• high level of natural noises;
• zvnіshnі pereshkodi priyomu signal: vysotnі budinki, trees, crafts spores;
• break out of the way of the cable;
• incorrect orientation of the transmission;
• the presence of an antenna of metal objects, buildings conduct electricity;
• outdated technology.

Ways to strengthen the tightness of the TV antenna

1. Change antenna re-roofing. As a rule, її direct kill transmission gear.
2. Attachment of the antenna podsiluvach. The stinks are electric devices, which connect directly to the antenna and send messages until the received signal is full.
3. Expand the number of antennas for a clear image, installed in the largest area.
4. Remember to attach to the darkened TV antenna.
5. Clean up all the objects metal objects, which may affect the reception of the TV signal
6. Check TV cable for integrity. At the time of the chimney, remember yoga for a new one. Important for a yakіsny signal.
7. Create an effect in-phase antenna array(SAR). Vіn polagaє in the fact that identical priymachi fold the folding system, as if working on the corner of the vanishing so that the phases of the signal were the same.

Knowing how to improve the television signal, it is possible to reduce the image transition on the screen to a minimum and enjoy a similar look directly from the station to the television center.

Pіdsilyuvach for antenna

Advantages and shortcomings of antenna subsidiaries

Like all radio technical attachments, devices may have their pluses and minuses. Before the transfer of the substationary antennas, the following shall be carried:

• with help of robots, I will attach a weak TV signal;
• minimal noise coefficient;
• reduction of the signal at a wide range of frequencies with a wide range of frequencies.

The main shortcomings, with which koristuvachs can close:

• shifting to the device from hard signals at the MV meter band (49-230 MHz);
• self-excitation of the pidsiluvach;
• prilad priyatlivy before strums of lightning electrical discharges;
• on the way out are passive spending.

How to choose an antenna pidsiluvach

The present-day pilots have a mass of technical authorities, who have brought documents to the annex. The problem is that the koristuvach often does not have enough knowledge to evaluate them correctly. Therefore, choose the attachments of the varto for the low most important characteristics.

1. Distance to receive, which is recommended. May be in the range of 30 to 150 km. Describe the position between the antenna and the broadcasting station, with any subsidiaries showing good results.
2. Frequency range. Є shirokosmugovі pіdsilyuvachi, scho pratsyuyut іz usіma standards movlennya. You can buy accessories for CETV, or better take short winds.
3. Strength coefficient. It’s wrong to say that the larger the number is, the shorter it is. The optimal value is at 27 dB. Such an attachment is suitable for a range of up to 50 km. Bigger serious models with CG close to 40 dB ensure a good signal in foldable minds. Alternately, put an overstretched pidsiluvach on the antenna, you can cause spratsyuvannya zakhistu TV or set-top boxes, blocking the signal.
4. Eating system. Proponuyutsya models for direct connection to a 220V socket with a living block or input 12V, 5V. It’s safe to say that it’s less likely to work with set-top boxes or TV from living on a signal cable.
5. The hull type is that vikonannya. Pіdsilyuvach mozhe razrahovany for installation on antennas in the minds of the street, mother zahist vіd drive that saw. Abo vykonuvatsya at the building for accommodation, rented for placement less than a TV set.

Optimal solutions for TSETV will be the substation of life on the signal cable. Today, this option on the connection port is propagated by anonymous set-top boxes.

Please! If it is old-fashioned, it is recommended to buy a power supply with a 5V power adapter via a signal cable.

Irrespective of the furious development of cable and satellite TV, it’s too early to write off the air of telecoms for rakhunkiv. For a yakіsny signal, the rest needs to be rebuffed in the coverage area. At the world in the distance from the TV, the quality of the signal falls, and the number of shifts increases. In such situations, the antenna support of the TV receiver is helpful. Let's take a look at what is attached, the principle of work, various modifications, as well as the possibility of creating a TB signal for a Moscow apartment, a foreign house or a dacha.

What is the antenna support and how does it work?

This attachment allows you to enhance the range of TV signals and reduce the level of the transition, to remove the most clear “picture”. Krym tsgogo, podіbnі pіdsilyuvachі vykorovuyutsya to reduce the cost in the cable. Typical structural diagrams of such extensions are shown below.

As you can see from the representations of the circuits, the signal that needs to be processed by the filter of external frequencies, after which it is reduced by the attenuator to the required level. They gave the signal to go to the control unit equal to the frequency response, the principle of dividing it into something rich in what the equalizer guesses. І at the rest of the stage, a stronger signal is carried out, after which the vin is on the TV receiver.

Rіznovidi

Irrespective of the diversity of the possession of this type, for functional reasons and the range of subsidiaries, it can be divided into the following types:

How to choose a good antenna from pіdsilyuvachem?

In order to take the maximum yield out of the house, it is necessary to protect the foot factors:

• Look for the nearest TV signal repeater. It is customary to take into account the maximum distance of 150 kilometers, but even more moderately, the shards are richly deposited, both in the type of mist, and the tightness of the television window. For example, perebubayuchi in the lowland, you can not take off the sound signal from a close-stitched repeater. In any case, the situation was corrected by installing an antenna under the help of the installed one.
• At some frequency range pracyuvatime obladnannya. It is necessary to be careful that the characteristics of wide-range antennas are compromised by narrow-directional ones. It’s not enough to talk about those that for the zone of the received cycle received the “all-Vilova Pich”, obviously, for the signal from the remote repeater, it’s better to take into account the importance of the design of the main frequency range (MV, UHF, UKH). But here it is also necessary to protect the particularity of the nature of the mass, for example, it is possible to get rid of the beaten signal only for the help of a direct antenna.

Having appointed the antenna, we proceed to the choice of a substation for it. First, for what it is necessary to pay attention to - the coefficient of strength (shown in decibels). As a rule, at a distance of up to 10 kilometers to the repeater, there is no need for additional support.

It is necessary to take care of yourself, so that you don’t even get overwhelmed by a high indicator of this parameter, the shards in case of high tension can become “awakened” by the building, and as a result of this, there are overshocks that appear at the sight of white snow in the pictures. Below is a table for possessing SWA, indicating the main characteristics of the skin model, as well as the coefficient of strength and distance to the signal.

Another important characteristic is the noise level (shown in decibels) of the vibrations of the process. Chim is a lesser show-off, Tim is better.

Naturally, if you choose, it is necessary to change the type of antenna, it is allowed to install a wide-range attachment to the audio-band receiver signal, but also navpacki.

How to build an antenna podsiluvach with your own hands - a cover instruction

Let's draw a sample of typical schemes of extensions for strengthening the television signal, for the most part from the simplest.

Designation:

• VT - microcircuit MAX2633.
• R - 1 room
• Capacitors C 1, C 2 and C 3 - 1 nF.

The circuit is confused in the case of a constant stream with a voltage of 28 to 52 volts. Notes: low noise level (about 2 dB) and a decent gain coefficient, about 13 dB, if necessary, reduce any amount of noise reduction R. The selected circuit does not require adjustment. Having recommended good guidance for himself when working with room antennas, tele- radio receivers. On the Internet, you can see the description of this scheme, as a wide-range one, which is not correct, based on the MAX2633 datasheet - assigned to the UKH range.

Now let's look at typical transistor circuits, which are wide-range.

Designation:

• Transistor VT1 - KT368.
• Opir: R1 -100 Ohm; R2 - 470 Ohm; R3 - 51 com; R4 - 100 Ohm.

The scheme is also breathtakingly simple and does not require tuning. KU and frequency characteristics lie in a twisted transistor. Attachments of this type are distinguished by a high gain coefficient and low frequency characteristics (which are corrected in multi-vibration circuits with a semi-terminal sound, when it is necessary to know them it is awkward, but stench is foldable in the field). Zhivlennya zdіysnyuєtsya vіd dzherel z prugoyu 9 volts.

The option of connecting a transistor behind the “hard base” circuit has a smaller KU, then a wider frequency range.

Designation:

• Transistor VT1 - KT315.
• Opir: R1 -51 Ohm; R2 - 10 com; R3 - 15 kOhm; R4 - 1 room
• Capacitance: C1-1000 pF; C2 - 33 pF; C3 and C4 - 15 pF.

The throttle is wound on a ferrimagnetic ring, the penetration of which is 600N. For the meter range, 300 turns are required, which is to be used for wires - PEV Ø 0.1 mm.

It is possible to reach a larger KU, so that you can choose attachments on a two-stage scheme, and the butt is pointed lower.

Designation:

• Transistors: VT1 and VT2 - GT311D.
• Opir: R1 - 680 Ohm; R2 - 75 kOhm; R3 - 1 room; R4 - 150 rooms
• Capacity: C1, C2 and C4 - 100 pF; C3 - 6800 pF; C5 - 15 pF; C6 - 3.3 pF.
• Throttles: L1 - 100 μH; L2 - 25 μH, L3 - with a coil on a frameless base, 4 mm in diameter, wound 2.5 turns, wired with PEV 2 Ø 0.8 mm.

The circuit is energized with a voltage of 12 volts, I will not need to install it.

Pokrokov's instruction for selection will be valid for all schemes:

• We buy all necessary electronic components.
• We prepare tools and supplies.
• We prepare a handy board, the overhead folding of the various mounting panels is not buggy, the shards in this way will increase the noise.
• We solder all the elements.
• We review the chosen design.
• Connected to the selected substation antenna and television receiver.

How to connect the antenna to the TV?

The most important moment is that the antennas for the TV are supposed to be closer to the new one. Tse z tim, scho cable spend can suttvo vplinut on the quality of the picture. Vymoga stands for both self-contained designs and serial models, for example, BBK or Terra. Vinyatok can be only a room antenna, which can make a short length of the cable, but, as a rule, such attachments can be installed at the reception area, so there are no necessary needs.

It is important to take into account the help of the connection, which is added to the annex.

Even if the connection of the power supply did not give any results, the directness of the antenna was reversed, as well as its hyvil's performance.

Usі manipuljatsії guilty are carried out only with the help of unscrupulous possessions.

Do not connect the power supply to the outside antenna, as it is not equipped with a lightning arrester. Vlasne such a priymach to the signal in the fire cannot be victorious.

The more I know the current elemental base, the more I marvel at the fact that at the same time work such electronic attachments, about how earlier it was possible only to dream. For example, an antenna substation, about which it is possible, may have a working frequency range from 50 MHz to 4000 MHz. So, maybe 4 GHz! In the hour of my youth, one could just dream about such a thing, and at the same time, such a pidsiluvach on one critical microcircuit can pick up a radioamator-pochatkivets. Moreover, I can’t get my hands on work over high-frequency circuitry.
The offerings below the antennae are superficially simple in preparation. May have a good coefficient of strength, low noise level and low noise level. Plus a wide range of robotics. So, yet another miniature rosemary, you can wake up like a yogo be-kudi.

Where is it possible to zastosuvaty universal antenna podsiluvach?

I may be in a wide range of 50 MHz - 4000 MHz.

• - As a substation of signals in a television antenna to receive both digital and analog channels.
• - Yak antenna podsilyuvach FM priymach.
• - in.

There is more than one-button vikoristannya, and in the radio amateur sphere there is a lot more stagnation.

Characteristics of the antenna podsiluvach

• Operating range: 50 MHz - 4000 MHz.
• Gain: 22.8 dB - 144 MHz, 20.5 dB - 432 MHz, 12.1 dB - 1296 MHz.
• Noise factor: 0.6 dB - 144 MHz, 0.65 dB - 432 MHz, 0.8 dB - 1296 MHz.
• Strum damping close to 25 mA.

Reporting characteristics can be looked at.
The low-noise pidsiluvach miraculously proved himself. The low strum of comfort is completely true.
Also, the microcircuit can visually show high-frequency interference without losing parameters.

Preparation of the antenna podsiluvach

Scheme

The circuit has a RFMD chip SPF5043Z, which can be purchased at .
As a matter of fact, the whole circuit is the microcircuit of the power supply and the filter for life.

Payment of a subsidy

The board can be made from foil textolite, wound without etching, as if I had made it.
We take two-sided foil-coated textolite and viplyuєmo a rectangle with a size of approximately 15x20 mm.

Then with a permanent marker it is small according to the line of breeding.

And then you want to work, but you want to see the paths mechanically.

We gave everything with a soldering iron and soldered SMD elements of size 0603.

Nalashtuvannya that viprobuvannya

The tincture is not needed, it is possible to freeze the input voltage, as it is to blame but in the range of 3.3 V and the flow rate is approximately 25 mA. Also, if you work in the 1 GHz band, it is possible, you need to use the input circuit, changing the capacitor up to 9 pF.
We connect the board to the antenna. The revision showed a stronger tone and a low level of noise.

It would be kinder to place a fee in a screened case like this.

You can buy a board for a ready-made substation at , but the cost is much more expensive, the lower microcircuit is fine. So it’s better to get confused, as I’m getting better.

Additional schemes

For the life of the circuit, a voltage of 3.3 V is required.

For which you can enter a stabilizer into the circuit.

Connecting the power supply to the antenna

For roztashuvannyam, pіdsilyuvach slid roztashovuvat in direct proximity to the antenna.
For the sound of statics and thunderstorms, it’s necessary, so that the antenna was closed along the constant stream, so it’s necessary to twist the loop or the frame vibrator. Antenna type "" will be a wonderful option.

Whether a signal, which is transmitted without darts, can be extinguished through different passages to yoga path and other factories. At zv'yazku z tsim blame pereshkodi, yaki especially strongly vplyvayut on the analog zv'yazok. To ensure a stable reception of TV broadcasts for the signal of TV antennas.

What is pouring in on the quality of the TV reception

The TV signal is transmitted more importantly in the decimeter range (DMV). Vin can be . Analog TV broadcasts with skin rock are getting worse, and companies that move, and slower, are increasingly giving priority to the digital signal. Vіn stіykіshiy to pereshkod and allow you to transfer the picture of the best quality. Standards for digital cable TV broadcasting are labeled DVB-T or DVB-T2.

The brightness of the signal is determined by the level of reception at the speaker, which is measured in decibels dB (dB). A repeater is the same thing that people call a TV tower. As soon as the repeater is switched over from the receiver (TV), then the lower signal will be equal to the rest.

Krіm range on the quality of the receiver, the presence of natural (trees, fire, fire) and piece (budіvlі, metal structures) transition between the repeater and the receiver is injected.

In an ideal situation, the repeater is responsible for being in direct line of sight in the form of a receiving antenna, with which it is applied. But such a situation is rare. The antenna itself is to blame, but it is straightened at the back of that repeater, the visibility of such a beauty, but stand closer, to ensure the maximum possible level of reception. The picture below is from the butt of receiving a telephone call.

Tsikavo:

Navit with an ideal roztashuvannі antennas priymacha and transmitting to the level of the call is pouring in and the weather - in bad weather the signal will be lower.

Also, the quality of the signal is not affected by the number of antennas, the quality of the cable, the presence of the rozgaluzhuvachiv and the successful couplings.

In the best option to the antenna, one receiver is connected to the antenna by a non-robust coaxial cable with a flexible support.

Jerela noise

Crim pereshkod pereshkodi signal to bring in and dzherela noise. Radio transmission attachments are brought up to them, as they work on the summіzhnіy frequency and transfers are brought in and inflow of electric lines. For example, when robotic extensions, yakі remind mezhny different harmonics - cereznomanіtnі collector electric motors, and, and other annexes.

See pidsiluvachiv

Signals are divided according to the range of the signal, which is stronger:

Broadband - include a kіlka bands. On which positive picture will end. It is impossible to reach equal strength on a great number of frequencies.

Bands - assigned to a specific range of frequencies.

Rich range - they have cascades for receiving and mixing signals from different ranges, sometimes and with the possibility of independent adjustment of the gain coefficient.

Also, pobutovі pіdsilyuvachi tv signal razrіznyayut for energized life:

5V- such power supplies can take life over a coaxial cable directly from a TV set or a TV tuner, the same voltage is transferred from most outbuildings. Ale, antennas with such podsiluvachs have recently grown wider. In this case, the subsidies are most often installed directly in the antenna.

12V- The widest option. For the current vicarious life, there is an additional life block at the same time as the voltage substructure (for adjusting the level of the receiver, it is a reasonable option).

Separate antennas for subsidiaries and for vicons:

On other payment- Installed in a box roztashovanu directly on the antenna. Їх nedolіkom є those, that the length of the cable and the number of days from the antenna to the TV set are reduced to a level equal to the signal.

Vinosnі- either it looks like a fixed stationary outbuilding (a small block, which you can tell by the dimensions of the TV tuner), or it looks like a small box, like it is installed directly on the cable. At any rate, the podsiluvach is connected to the line between the antenna and the TV.

It is possible to introduce and report the classification of indicators for TV antennas, but for the average statistics, there is enough information.

Schemes

The main characteristics of any podsiluvach are the coefficient of strength and noise. For the radio signal, the subsidy can be repaid at the frequency of the required range. First of all, more than a wide range of frequencies - more powerful.

In a more detailed version, the scheme of the pilot is the same scheme as we modeled. Ale, before her, to be guided by the working frequency of the switching transistors. Schemes can be composed of one or more cascades. Single-stage circuits are simple and unimaginative in the field, but may have a weak gain coefficient.

On a little lower, the butt of a single-cycle antenna substation. As a transistor, you can win the KT368 or its foreign analogue 2N918.

At that hour, yak Ku can zbіlshiti skіlki zavgodno strongly adding additional cascades. In addition, the number of cascades can increase and change the code, so you can’t get used to fighting with them at the sight of different filters, the correct distribution of the other payment and the binding of low-noise transistors and other radios. The small picture below shows the schemes of the popular two-stage wide-swept pods of the SWA series.

The modern elemental base allows to be used on the basis of integrated microcircuits, which allows for the need for a folding adjustment of the attachment, which can be accurately carried out without difficulties.

Before that, all discrete components may have a strong rise in parameters, for example, if it is popular, but it is also outdated (want to win by radioamators and today) a series of transistors KT315 in some modifications is small in rise for a strength factor greater than 10 times.

Think about it, two identical transistors could compete with such a difference. Obviously, such a rozkid has changed in the present industry and carried out more precise operations for the production of conductor crystals of the necessary structure.

Integrated microcircuits are good, because the transistors can enter the current warehouse on a single crystal and may have approximately the same parameters.

vibir

When buying a subscription for a TV signal, you can’t be fooled by the principle the bigger the better. Otzhe, є logical nutrition on scho to marvel at the choice of subsidyuvach for a TV antenna? Let's get smart!

An overworld stronger signal was brought to its creation, sometimes it is called overwhelming or clipping. To that, it is necessary to pick up vihodyachi from the vihdnih data about real money to receive that necessary coefficient of strength. You can call with a call to the appointed station to the repeater.

So it will be kinder, as in pіdsilyuvachі it is transferred pіdstroyuvannya or more widely regulation of the coefficient of strength - and the model is richly universal.

They gave you the need to sign up for it, what range you need to use and at the vikonan’s own prilad. In the table above, the technical characteristics of the popular substationary antennas for the antennas (among the people "polka") are indicated.

There are unacceptable situations, if the TV broadcast is a bad signal, which is in the air. In such a time, it is necessary to have a yak_sny p_dsiluvach of the TV signal.

The failure of the TV signal of cable TV at the apartment is due to various reasons:

1. Poor choice of TV antenna.
2. The switch houses are far from the repeater.
3. A lot of natural noises.
4. Antenna cable wiyshov out of tune.
5. Transmitter incorrectly lashed.
6. Vikoristovuetsya old technology.

In order to increase the links, it is necessary to win one of the twisted methods.

How to improve the TV antenna signal:

1. We are going to change the antenna expansion. Її it is necessary to send it exactly at Bik TV news.
2. Buy a kind podsilyuvach signal TV antenna. The whole electric device, which is connected directly to the annex.
3. Increase the number of antennas on the dash to get a clear image. Leather from outbuildings, it is necessary to place it in the next place in the booth.
4. Replace the antenna with a larger hard analog.
5. The recipient may be interested in various metal details, which are measured in terms of cost. To that, all items should be taken away, so as not to break the link.
6. If the antenna cable goes out of tune, then you can’t talk about the quality of the signal. In order to blame the problems, it is necessary to revise yoga. At the time of the zamikannya, or the shave will need to buy a new cut.
7. Vikoristovuvaty effect common-mode antenna ґrat. Dekіlka priymachіv vykoristovuyutsya for folding folding system, schob zagalno navantazhennya on the phase vyyshlo single.

These are the main ways to improve the reception of the antenna. One of the most effective ones is vikoristovuvati pіdsilyuvach.

How to choose an antenna pidsiluvach

Prior to the choice of a digital television receiver, it is necessary to do so in a practical way.

To buy a similar option, you need to check the bill with the parameters:

1. Vіdstan tv_zora vіd repeater. The indicator may be between 10-150 km.
2. Correctly select the frequency range.
3. Riven TV signal at the priladі. A stable option for giving a house is 100 dB per microvolt.
4. The gain coefficient is to blame for adding 40 dB or more.
5. Slid to recognize the type of attachment, for which you need more power.
6. The noise level can be reduced by 3 dB or less.
7. The indicator of slowing down the struma is 30-60 mA.
8. It is necessary to place the attachment to the receiver, or directly in the antenna housing.

Like in a booth there is a digital TV box, the next thing is to have a voltage indicator of 5 V. When you use a DVD-T2 digital set-top box with such a number, you won’t be able to additionally switch on the live block for the power supply.

Popular models for TV signal:

1. Televes 5523. This is a product of an Italian company, which may have a good gain coefficient of 16 dB. It also automatically reduces the level of third-party noise. Yakіsno zbіshuє dimness of the TV antenna.
2. Terra HA 123 The gain factor is more than 20 dB, otherwise, the device can be blocked for different frequencies. The model is more suitable for dachas.

Suitable models for satellite and broadcast television:

1. Gecen A05-02. The signal rises up to 21 dB. In order to improve the quality of television broadcasting TV, to bring about additional life.
2. Polish model SWA. Sound them on the antenna grids. The range of power factors can be from 49 to 790 megahertz. For mounting robots, zastosovuyut studs or z'ednannya on the cut.

Benefits of possession:

1. Navіt akscho tvіzіyny signal is too weak, pristriy zbіlshit yogo. So let yourself be savored by a look at the be-yakim misci, to strike a very distant view of the television. The food supply is especially relevant for Vlasnik dachas.
2. When working, I will add a minimum noise coefficient.
3. Attachment improves the quality of the broadcast in a number of bands.

Leather electric attachment may not only be a plus, but a minus:

1. As soon as the device needs to have attenuated signals of different frequencies, it can be periodically reset.
2. For filthy weather minds and for an hour, threatens the brightness of the picture, it can get worse, shards of light react to electric discharges in the decimeter range. Zovnishniy street TV signal at the dacha is more effective than during daily thunderstorms.
