Antenna amplifier SWA LSA. All about antenna amplifiers Amplifier swa 555 consumer reviews

In the zone of uncertain reception of a television signal, in order to obtain a high-quality picture when watching television, it is necessary to install an external antenna on the mast, on the vibrator of which an antenna amplifier is additionally installed. Installing an additional amplifier provides a high-quality picture on the TV when the TV transmission tower is up to 100 km away.

Antenna amplifiers of the SWA line are widely used due to their high reliability and low price. They are produced for different channel ranges and different gains, from 34 to 43 dB in the decimeter range and from 10 to 15 dB in the meter range. The photo shows an amplifier type SWA-555 / LUX.

The antenna amplifier of the SWA television signal must be powered with a constant voltage of 12 V. There is a circuit solution that allows you to supply the television amplifier with a supply voltage via a coaxial cable simultaneously with the television signal. The photo shows how to connect a TV wire to the SWA antenna amplifier.

The central core is clamped with one screw, and the shielding wire is stripped of insulation, wrapped and clamped with screws using a strap. The main thing here is to prevent the screen wires from shorting with the central core. In this way, antenna amplifiers of any type installed directly on the antenna are connected.


On sale there are special power supplies - adapters with adapters that allow you to supply power to the antenna amplifier. The photo shows one of them. Connecting such an adapter is simple, a cable coming from the antenna is inserted into one coaxial wire, and a cable going to the TV is inserted into the second. The adapter itself is plugged into an outlet. It is impossible to confuse the wires when connecting; the coaxial wires coming out of the adapter have different connectors, which exclude an erroneous connection.

Power supply - adapter for antenna amplifier

If you open any power supply with an adapter, you will see a power transformer, four diodes, an electrolytic capacitor, a simple capacitor, a choke and a microcircuit - a voltage regulator.


All parts of the decoupling circuit, except for the power transformer, are installed on the printed circuit board.

Electrical circuit diagram of the power supply
for antenna amplifier with adapter

The power supply shown above in the photo - an adapter for powering an antenna amplifier is assembled according to a classic electrical circuit diagram. The mains alternating voltage of 220 V is supplied to the power transformer T1, which lowers it to 12-15 V. The diode bridge VD1-VD4 rectifies the voltage, the electrolytic capacitor C1 smoothes the ripples, after which a constant voltage of about 16 V is supplied to the integral voltage regulator DA1.


To eliminate video signal loss and loss of DC voltage, an LC filter is provided at the input of the television receiver, made on elements L1 and C3. Inductor L1 does not pass a high-frequency television signal to the power supply circuit, but without loss allows direct current to flow to the central core of the television cable coming from the television antenna amplifier. Capacitor C3 prevents the flow of direct current from the power supply to the input of the TV, but passes the TV signal without loss.

When you make your own power supply with an adapter, parts of any type can be used. Typically, the current consumption of antenna amplifiers does not exceed 150 mA, which is less than 2 watts, so the transformer for the power supply is suitable for any power with an output voltage of 15-18 V. The inductor can be made by winding a dielectric base, for example, a strip of fiberglass 5 mm wide, 25- 30 turns of enameled copper wire with a diameter of 0.1-0.5 mm.

Disadvantages of the presented design of the power supply with an adapter

The disadvantages of a power supply unit - an adapter of this design include the presence of an unshielded section of the central core of the television cable in the place of soldering into the printed circuit board, which, in the presence of interference, for example, from a working vacuum cleaner, can lead to interference with the video signal. The penetration of interference can be eliminated by installing an additional shield on the printed circuit board at the place where the wires are soldered.

Self-made adapter

An adapter adapter with wider technical capabilities can be made with your own hands from any antenna splitter crab. If you need to power a television amplifier and simultaneously connect several TVs to the antenna, then this is easy to do by supplementing the crab circuit with just three parts that will perform the decoupling function.

The device and scheme of the crab

The TV crab is a metal box with F-connectors. Inside, on the central terminals of the connectors, parts (high-frequency transformers) of a television signal splitter are soldered. A high-frequency transformer is in shape a ring or tube made of ferrite with a magnetic permeability of 600-2000, on which from 1 to 10 turns of enameled wire with a diameter of 0.2-0.3 mm are wound evenly spaced around the entire circumference.


In the photo of the crab, from which the back cover was removed, you can clearly see how the ferrite transformers are soldered to connect three TVs. This crab is assembled according to the electrical circuit diagram below.

All manufactured crabs are assembled according to the above electrical circuit diagram, there may be minor deviations - additional separating and filtering capacitors, chokes, and terminating resistors are installed.

How to make your own adapter
to supply voltage to the antenna amplifier

When making an adapter for supplying voltage to a decoupled antenna amplifier, I decided not to install an additional connector for connecting a power supply, but to use one of the connectors for connecting an F-plug. To do this, one of the transformers had to be removed, limiting the crab's ability to connect only two TVs.


As a result of the alteration, only two TV sets can be connected to the crab, and its scheme has changed.

It remains to install the LC filter in the crab and the adapter will be ready for use. Since the crab body is made of duralumin, it was necessary to connect the capacitor output to it through an additionally installed brass terminal, screwed to the adapter body with a screw and a nut with a shaped washer.


As a result of refinement, the electrical circuit diagram of the crab has acquired the following form. As can be seen from the diagram, the T1 transformer remained native, but a choke and two capacitors were added.

For better circuit matching, you can solder a 150 ohm resistor between the output terminals XW2 and XW3. You can install the adapter in any convenient place, directly at one of the TVs, or, for example, at the cable entrance to the apartment. If you need to connect only one TV, then the transformer T1 can be removed, and the right terminal of the capacitor C1 can be soldered directly to the central terminal of one of the XW2 or XW3 connectors, to which you can connect the cable going to the TV.

Connecting the power supply to the adapter

Since I decided to connect the power supply to the crab through one of its F-connectors, to implement this idea, I had to make an adapter from an ordinary double wire coming from the power supply to a coaxial cable.


To do this, take a piece of antenna cable 5 cm long, cut one end of it and put on F-wrap. To the second end, as shown in the photographs, solder the wires coming from the power supply with a shift. The positive lead is soldered to the center core of the antenna cable.

If you don’t want to mess around, you can install a standard connector for connecting power supplies in the crab case and apply voltage to the antenna amplifier through it through an adapter made by yourself.

There are places where the TV signal is received in very low quality. In such cases, it is necessary to use an external antenna, on the vibrator of which the antenna amplifier is located. It allows you to amplify the signal even at a distance of 100 km from the tower.

Widely used amplifiers are SWA amplifiers. They have a low price and provide sufficient reliability. They have different gain and are designed for different range of channels. In the decimeter range, the gain is 34-43 dB and 10-15 dB in the meter. In the photo below you can see the amplifier model SWA-555/LUX.

The signal amplifier SWA operates from a constant 12 V supply. There is a circuit that allows you to apply voltage to the amplifier through a coaxial cable along with the signal. On the market you can find an adapter that is also a power supply that solves the problem. It is shown in the photo below.

Connecting the adapter does not require skills. We insert the wire that goes to the TV into one coaxial cable, and the antenna wire into the other. The adapter plugs into an outlet. It is not possible to confuse the wires, since there are different connectors at their ends.

By opening the power supply with an adapter, you can find a power transformer, simple and electrolytic capacitors, 4 diodes, a choke, a microcircuit that acts as a voltage stabilizer.

Everything except the transformer is located on the printed circuit board.

Electrical circuit diagram of the power supply with adapter

The adapter shown in the photo above is assembled according to the classical scheme. The alternating mains voltage of 220 V is supplied to T1 (transformer), which in turn reduces it to 12 V - 15V. VD1-VD4 (diode bridge) will act as a voltage rectifier. Capacitor C1 is used to smooth out ripples. After that, a constant voltage is obtained, the value of which is about 16 V. Then it goes to DA1 (integrated stabilizer).

LC filter is made on elements C3, L1. It is installed at the input of the receiver. It eliminates the loss of DC voltage and loss of video signal.

L1 (choke) prevents the high frequency signal from flowing to the power supply circuitry. At the same time, direct current freely flows to the central core of the TV cable, which comes from the amplifier. C3 (capacitor) prevents direct current from flowing from the power supply to the TV input. There is no signal loss in this case.

For self-manufacturing of the power supply, you can use parts of various types. Any transformer with an output voltage of 15-18 V can be used. This is due to the fact that the antenna amplifier does not exceed the current consumption of more than 2 W and 150 mA. As a choke, you can use a piece of dielectric, for example textolite, the width of which is 5 mm. From 25 to 30 turns of enameled copper wire are wound on it.

Disadvantages of the presented design of the power supply with an adapter

Among the shortcomings, one can note the presence of a section that does not have a screen on the central core of the television cable. This area is located in the soldering area with the printed circuit board. When operating machinery such as a vacuum cleaner, this may cause interference to the video signal. This can be avoided by installing an additional screen.

Self-made adapter

If you need an adapter - an adapter that has wide technical capabilities, it can be made at home from a crab - an antenna splitter. To power the amplifier and additionally connect several TVs to the antenna, the crab circuit will have to be supplemented with 3 parts.

The device and scheme of the crab

A TV crab is a metal case with F-connectors. Inside it, high-frequency transformers of the tele-signal splitter are soldered. They are located at the center pins. In appearance, a high-frequency transformer is a tube or a ring made of ferrite. It has a magnetic permeability of 600-2000. Rounds of enameled wire are wound on top, the diameter of which is 0.2 mm–0.3 mm. They are evenly spaced around the entire circumference. The number of such turns can reach from 1 to 10.

Pictured is a crab. The back cover has been removed. As you can see, the ferrite transformers are soldered in order to connect 3 TVs. It was made according to the circuit diagram, which is shown below.

All crabs are made according to this scheme. It may have some deviations - installed chokes, resistors, filtering, separating capacitors.

How to make your own adapter
to supply voltage to the antenna amplifier

To make an adapter designed to supply voltage to the antenna amplifier, I did not install a connector for the power supply. I decided to use one connector to connect the F-plug. To do this, it was necessary to remove one transformer. The number of connected TVs has dropped to two.

As a result, the concept has changed.

Before using the adapter for its intended purpose, you should install the LC filter in the crab. The body of the crab is made of duralumin, so I made a brass terminal. It was fixed to the body with a screw and a shaped nut.

As a result, the scheme has changed slightly. Transformer T1 remained in its place, 2 capacitors and a choke were added.

In order to carry out circuit matching, it is desirable to install a 150 ohm resistor between the output pins XW3 and XW2. The adapter can be installed in any convenient place. Both at the cable entrance to the apartment, and near the TV.

If you use only one TV, T1 can be removed from the circuit. Solder the right terminal C1 (capacitor) to the central terminal of connector XW3 or XW2. The cable will be connected to the connector to which the capacitor will be soldered.

Connecting the power supply to the adapter

I wrote earlier that I want to connect the cable through the F - connector. Therefore, from the double wire that came from the power supply, I made an adapter for a coaxial cable.

The SWA and LSA antenna amplifiers are not independent devices, unlike external amplifiers such as Alcad. They are an electronic amplification board and need a power supply and a protective cover.
are used in lattice antennas ASP-4, ASP-8, which are often called Polish antennas. The gain of such antennas without an amplifier is small, and its receiving properties are mainly determined by the installed amplifier.
Antenna amplifiers swa have an input impedance determined by the design of the antenna 300 ohms, an output impedance of 75 ohms for connection to a television receiver, use a supply voltage from 9 V to 15 V and are designed to amplify frequencies of 49 - 790 MHz.

Amplifiers

What grid antenna? Array antennas, sometimes referred to as grid antennas or screen antennas, are a flat vibrator structure with an overall grid screen that acts as a reflector. Antenna amplifiers swa are installed directly on such an antenna and are fed with direct voltage through the antenna cable. Structurally, the amplifiers for lattice antennas, manufactured by different manufacturers, are made in the same way, in the form of a small board measuring 60 x 40 mm with surface-mounted smd elements.

swa amplifier installed in outdoor antennas, arrays, grids or as they say "Polish antennas". Depending on the distance to the transmitting television center, various models of the amplifier board are used, which have different gain factors and allow receiving television programs at a distance of 0 to 150 kilometers from the transmitter.

Antenna amplifiers characteristics

What parameters affect the quality of amplifiers? To evaluate the quality of the swa amplifier, that is, the quality of the image on the TV screen, the gain and noise figure parameters are very important. The noise figure should be as low as possible, and the gain should not be maximum, its value should not be more than such that the value of the signal entering the TV input is in line with the norm.

Purpose of the antenna amplifier lsa

Antenna amplifiers LSA produced to repair failed popular active television antennas Locus. Active antennas fail as a result of a powerful electromagnetic discharge during a lightning strike, malfunctions of the power adapter, due to aging of the elements, due to a violation of the sealing of the protective mounting box and wetting of the circuit elements.

Replacing the standard Locus amplifier with an lsa amplifier

Antenna amplifier LSA 417(LSA 020) is used to replace the failed amplifier models L 025.09, L025.12, L025.62 and other Locus series 25 antenna models. It is used for models manufactured after 2007. A characteristic feature is the presence of plastic guides in the amplifier mount. The Locus 025 series of antennas is equipped with one amplifier and one LSS-422 matching board, which has no active elements and which practically does not fail.
In older models of Locus L 025 antennas, LSA 417 amplifiers are used with a different method of mechanical fastening and do not differ in circuitry.

Antenna amplifier LSA 421(LSA-071) is designed for broadband amplification of television signals and is used in antennas Locus L012.20, L023.09, L023.12, L024.09, L108.00.
The amplifier has a noise figure of no more than 2 dB, consumes a current of 20 mA from the power supply at a supply voltage of 12 V.

Antenna amplifier LSA 416 is used for replacement in indoor antennas Locus L405.05

In television antennas Locus 024.09 and Locus 024.12, instead of two LSA 419 amplifiers, an LSA 839 amplifier board is available.

Digital television of DVB-T2 standard in Ukraine.

Until June 17, 2015, in accordance with the international agreement (Geneva-2006), Ukraine is obliged to switch completely to digital broadcasting of the DVB-T standard and DVB-T2. This is the plan for the development of the national television and radio information space. Now in our country, a gradual shutdown of broadcasting in analog format is beginning. For quite a long time in Ukraine they have been broadcasting in test mode DVB-T and DVB-T2 digital standards. Standard DVB-T2 becomes the basis for broadcasting and development of digital television in Ukraine.

DVB-T2 It is the second generation European terrestrial standard for digital terrestrial television. Ether is a hypothetical all-penetrating medium (the upper layer of air). Unlike the first generation DVB-T standard, the standard DVB-T2 Designed to increase network capacity by 30-50% while maintaining core infrastructure and frequency resources.

In addition, among the benefits of switching to DVB-T2 the following can be distinguished:

  • increase in the number of channels of the broadcast package.
  • the possibility of organizing regional (local) broadcasting.
  • opportunity to develop high-definition television.
  • release of ethereal frequencies.
  • Available in all corners of Ukraine (covers 95% of the territory)
  • Very easy to connect
  • Excellent picture and sound quality
  • All popular national TV channels are available
  • Provided without a subscription fee

Digital broadcast format DVB-T2- the most modern of all existing today, which, of course, the whole world will come to in the near future, since its capabilities are much wider than that of standard DVB-T. The main and undeniable advantage of technology DVB-T2 is that its functionality is not limited to broadcasting free digital TV channels. In addition to watching 32 digital TV channels in the highest quality, in the near future it will be possible to record your favorite programs for delayed viewing, order movies from network servers, watch online TV, and listen to digital radio. AT DVB-T2 the possibility of transmitting several independent transport streams of different nature and structure is laid down. Each digital stream is placed in its own trunk stream - the so-called PLP physical layer channel. For this, a function for preprocessing input data has been introduced. Standard DVB-T2 fundamentally differs both in system level architecture and physical layer properties, as a result of which DVB-T receivers are incompatible with DVB-T2.

DVB-T2 features:

  • OFDM modulation with OPSK, 16-QAM, 64-QAM or 256-QAM groups.
  • OFDM modes 1k, 2k, 4k, 8k, 16k, 32k and “32k ext”. The symbol length for 32k mode is about 4 ms.
  • Relative lengths of guard intervals: 1/128, 1/32, 1/16, 19/256, 1/8, 19/128 and 1/4. (For 32k mode, maximum 1/8).
  • Forward Error Correction (FEC) with cascaded application of LDPC and BCH correction codes (as in DVB-S2 and DVB-C2).
  • DVB-T2 supports channel bandwidths of 1.7, 5, 6, 7, 8 and 10 MHz. Moreover, 1.7 MHz is intended for mobile television.
  • transmission in MISO mode using the Alamouti scheme, that is, the receiver processes the signal from two transmitting antennas.

Service capabilities of DVB-T2:

  • Multichannel multiplexing.
  • SDTV standard definition television in 4:3 and 16:9 screen formats.
  • HDTV standard definition television.
  • Ultra high definition television UHDTV.
  • 3D TV in DVB 3D-TV standard.
  • Interactive hybrid TV in Hbb TV standard.
  • Video on demand.
  • Teletext.
  • TV guide.
  • Subtitles.
  • Stereo sound.
  • Dolby Digital sound.
  • Surround sound.
  • Multisound (selection of broadcast language).
  • Digital radio.
  • Synchronization of time and date with digital TV broadcasting.
  • Data transmission in DVB-DATA standard.
  • Forward and reverse communication channels for interactive services in DVB-RCS and DVB-RCT standards.
  • Broadband Internet access.
  • Notification system.

DVB-T2 digital signal reception:

Reception of a digital signal is carried out by an on-air collective or individual (outdoor or indoor) television antenna, decimeter range (UHF), connected to various receivers:

  • LCD/LED TV with built-in DVB-T2 tuner.
  • TV set-top box (receiver, tuner, receiver) DVB-T2.
  • TV tuner DVB-T2 for computer.

Advantage of digital signal DVB-T2 consists in the fact that the digital television signal is received on the decimeter range antenna (UHF) and transmitted without distortion, as a result of which the stability of the image and sound on TV receivers increases. And also the advantage is the absence of image interference associated with atmospheric phenomena. The digital signal is protected from this and you see a very good quality picture on the TV screen. In addition to a high-quality picture, you get a five-channel sound. Plus, you get additional information EPG (electronic TV program) - gives information about the current program, and a TV guide for 7 days. Broadcasting is broadcast in multi-channel networks consisting of five multiplexes, these include: 32 standard channels DVB-T2(MPEG-4), including 28 nationwide and 4 regional broadcast TV channels. Further plans include a significant expansion of the number of television channels at the expense of paid ones; one way or another, 32 channels remain available without any subscription fee.

Now in the digital standard DVB-T2 in Ukraine, viewers have access to 32 TV channels .

The price of equipment for viewing in the DVB-T2 standard

An antenna amplifier is a device that is installed on an antenna in order to amplify the signal and, as a result, improve the quality of the picture on the TV screen. It will be especially relevant in areas far from TV towers. As a rule, these are villages and villages located far from civilization.

Installing an antenna amplifier is necessary to improve signal quality.

There can be many reasons for poor signal reception. Even residents of large cities face such a problem, although it would seem that they are in close proximity to the towers. The most common causes of interference:

  • the signal source is too far from the receiving point;
  • obstacles located on the signal path - trees, high-rise buildings, etc.;
  • landscape gap between the signal receiving point and the tower;
  • weak signal.

The choice of antenna amplifier depends on many factors. However, the first thing you need to understand is which antenna is installed. There are two types of them: passive and active. A signal amplifier is already built into the design of the active antenna by default. If you have problems with the signal, then most likely you are the owner of a passive antenna. Such an antenna should only be installed if the transmitting tower is within sight and there are no obstacles between it and the antenna.

The next thing to find out is the distance to the nearest tower.

ADVICE. Depending on the distance to the tower, a device with a suitable gain should be selected. As a rule, it is worth buying an antenna amplifier only if the distance from the tower to the house is more than 10 km. If the distance is less, then the problem is in an incorrectly selected antenna and the position amplifier will not correct it.

Gain is a characteristic with which to be careful. This is the case when more is not better. With a deficiency, the signal will not be strong enough, and with an excess, noise will appear, which will still interfere with high-quality broadcasting. For this reason, many models of amplifiers with different characteristics are produced for one type of antenna.

For the correct selection of the coefficient, it is necessary to use a special table. There is nothing difficult in this.

Types of amplifiers

We will not go into the intricacies of the design of the antenna amplifier - for the layman, this information will be useless. Let's talk about two types of amplifiers and their purpose.

SWA Amplifier

SWA antenna amplifiers are used in the ASP-4 and ASP-8 lattice antennas, which are often called "Polish" antennas. By themselves, these antennas have a very low gain, and they cannot do without an amplifier.

The two most important characteristics when choosing an SWA amplifier are gain and noise figure. When buying, pay attention to them. We have already talked about the first one above. With the second, it's still easier - the less, the better.

Amplifier LSA

This type of amplifier has a very narrow scope. They are produced to repair failed Locus antennas. Certain LSA models can amplify their corresponding Locus antenna models.

Power Supply

As a rule, the design of the antenna amplifier is equipped with a built-in power supply. The device connects to the network and, due to its low power, consumes only about 10 watts. There are built-in and external power supplies. Built-in power supplies are small, low-power devices. With unstable operation of the electrical network, they are of little use. However, if power surges are rare, it will be enough.

External power supplies are large in size and power consumption. They provide stable operation of the antenna amplifier even in unstable network conditions. Such power supplies are designed for different input voltages: 5, 12, 18, 24 V. This parameter must exactly match the supply voltage of your particular amplifier.

Antenna booster installation

Externally, the amplifier is a small electronic circuit. It is attached directly to the antenna itself with bolts and nuts. The amplifier will show greater efficiency if it is installed near the antenna on the mast, between the matching device and the feeder. The signal passing from the antenna through the feeder significantly reduces its level. After installation, you need to check whether the signal has improved. Without equipment, this can be done by simply turning on the TV.

If the antenna is already installed, it will not be difficult to connect the amplifier and, using a special adapter, power the power supply. However, if the antenna is not connected, then you will have to puzzle out the cable to the TV. If you are not confident in yourself, then the best solution would be to call a telemaster who will quickly and efficiently complete this task.

Connecting a TV cable to a TV

The first step is to choose a TV cable. This is a very crucial moment, since even an expensive TV will not provide you with a high-quality picture without the right wire.

The most common on the market are coaxial cables of various manufacturers with a characteristic impedance of 75 ohms of the brands RG 6U, SAT 50, SAT 703B and DG 113. The brands are listed in ascending order of quality. The marking is applied to the cable sheath along the entire length.

IMPORTANT. We will not describe all existing antenna cables, as this is not possible. However, please pay attention to the following - the cable must have a characteristic impedance of 75 ohms and the outer diameter of the sheath must be at least 6 mm. By adhering to these two criteria, you will be able to choose the right cable.

After you have chosen the cable, it must be connected to the plug, since bare wires cannot be connected to the TV. In our time, F-plugs are the most widely used. Plugs are available in three different sizes for different cable diameters. Be careful when buying - make sure the plug fits your cable. After the purchase, it remains to install the plug. You can do this according to the diagram below.

Antenna ground

However, this is not all. The antenna must be grounded before use. This is a very important and responsible procedure, and it is worth approaching it with all responsibility.

IMPORTANT. Be careful! In the previous stages, the maximum that you could spoil is the cable. When grounding, there is every chance of getting an electric shock - which can be fatal. Therefore, in no case do not try to do the grounding yourself! Call the master who will do everything quickly and efficiently.

If you live in an apartment building, as a rule, the antenna will be installed on a balcony or loggia. In such cases, grounding is not necessary, since it is already provided for when building a house. Grounding will be relevant in a private house or in a summer cottage.

That's all. In this article, we talked about the existing types of antenna amplifiers and how best to install them. We hope the article was informative and helped you in this difficult matter.
