A weak television signal, which spoils the “picture” on the TV screen, can be easily amplified using a special device. This simple but effective invention is called an antenna amplifier. It reduces the level of interference, the image becomes high quality.

The editors of the Yanashla website bring to your attention a review of high-quality signal amplifiers for TV antennas for 2021 and recommendations for choosing this equipment.

What types of amplifiers are there?

Devices that amplify television signals vary in classification and design.

There are devices for digital TV antennas and for analog signals. They have a power supply, both external and internal. The external unit is larger than the internal one, its input voltage depends on the amplifier, and can consume 5, 12, 18 or 24 V. The internal unit consumes up to 10 V, it requires a stable voltage of electricity. It may fail during power surges. If the unit burns out, you will have to replace the entire antenna completely.

Types of amplifiers depending on the received frequency

Devices according to classification are distinguished into:

• Broadband

These models are capable of covering a wide range of amplified frequencies. As a rule, they are used if the TV antenna signal is good, but does not provide an ideal image.

• Band

Designed to receive frequencies either meter (MV) - from 30 to 300 MHz, or decimeter (UHF) - from 300 to 3000 MHz. Can be used if the TV signal is very weak. Digital TV requires a UHF frequency range.

• Multi-band

Models with separate adjustment of different ranges.

According to the required voltage, they are divided into the following types:

• Five-volt.

They are connected using a coaxial cable and attached to the antenna.

• Twelve volt.

These devices work with a power supply.

• the presence of “ears”, thanks to which the device is mounted on the wall with ordinary screws or bolts.

• not detected.

I bought this miracle piece of technology two weeks ago, and I already have some impressions that I want to share. The model has one input, but inside the amplifier the entire range of the television signal is divided into two subranges: MV and UHF. In each of the sub-bands there is a gain and frequency response slope adjustment, two attenuators and a stepless gain and frequency response slope control. The output signal is formed by summing the signals from the VHF and UHF subbands of the amplifier. The case is strong, moisture-resistant and beautiful.

Terra HS004

Alcad AL-200

The wideband residential amplifier from the Spanish company Alcad is one of the most popular on the Russian market. It is highly reliable and is designed to amplify television signals in the UHF and meter wavelength range; it has one antenna input and two outputs.

Good afternoon I recently purchased this amplifier model for my TV, which has been receiving a poor signal lately. Overall it was more than helpful. There is separate adjustment for the MV and UHF ranges. Factors such as high power (gain up to 24 dB) and low noise level encourage the purchase. It is one of the most effective solutions for amplifying the signal received by one antenna for the whole house. Fully compatible with the DVB-T2 standard.

Alcad AL-200

Rexant 05-6202

A television divider is a convenient means for dividing a signal into several equal parts. Antenna splitters, also called television splitters, are used in cases where it is necessary to connect one television cable coming from the antenna to several televisions or receivers at once. This is especially true in multi-room apartments or country houses. The divider has one input for an F-connector and three outputs also for F-connectors. The signal supplied to the input of the divider is divided into two equal parts and transmitted to the outputs. Standard F-connectors are used to connect cables.

Pros and cons of TV signal amplifiers

According to experts, the advantages of using amplifiers are:

• Noise coefficients are negligible;
• Very weak TV signals are being received;
• You can amplify the signal in several ranges simultaneously.

But where there are pros, there are always cons:

• When using a “broadband”, you can overload the required signal level;
• Afraid of thunderstorms;
• The TV signal may be lost;
• Greater sensitivity.

It is important not to forget that this device is not a super-device; it only performs correction functions, helping the TV antenna to “fix” a good signal.

Criteria for choosing a good amplifier

To avoid making mistakes when choosing an amplifier, you should pay attention to the technical characteristics of the device.

1. What range is it intended for?

If the reception area is not far from the repeater, then a “broadband” will do. If you are receiving a television signal from afar, then you need a narrow frequency range, meter or decimeter, depending on the television.

1. Noise effect.

When transmitting a TV signal, noise is also received, which the device must correct. The best one is with a noise effect of no more than 2 dB. However, models with a noise figure of up to 3 dB are also valued.

1. Gain.

High-quality transmission requires the following parameters: for UHF - 30-40 dB, for meter - 10 dB. Moreover, in the first option, the coverage of TV channels will be up to 60, in the second – 12.

• Specifics of the TV antenna.

If the antenna is active, then it needs an amplifier that helps to obtain a high-quality television signal. A passive antenna works without it. However, it can be repurposed. For an active antenna, use a device with an adapter and connect it to the network.

Tips for choosing

Below we will look at what factors should be taken into account when choosing a high-quality amplifier for receiving a digital signal.

1. Nutrition. First you need to understand that any active amplifier requires power. To get it, you mainly use a 12 V mains adapter. But some models are capable of receiving current through an antenna cable.
2. Frame. An important parameter that may affect the further performance of the unit. The fact is that a large number of amplifiers are located outdoors, so they must have a moisture-proof housing. But there are models located indoors; they do not need such a function.
3. Gain. Perhaps one of the most important characteristics. Remember, there is no need to chase large values. Instead, it is better to find out the distance to the nearest television center and check with the one stated by the device. Having taken a reserve of 5-10 km, you can safely buy the device.
4. Frequencies. Another difference between most models is support for certain frequencies. More often, users choose broadband amplifiers, since they pick up almost all signals and frequencies.

The best budget antenna amplifiers

Remo BAS – 8102 – 01

In terms of compactness, it has no equal. The price tag looks nice. The main disadvantage is that it is almost impossible to purchase in specialized retail outlets. The order is carried out mainly through an online store selling antennas and all kinds of accessories. Only large domestic retail outlets such as M.Video and DNS please customers.

It is extremely popular among specialists in this field. But there is no need to talk about his impeccability.

In its appearance and size it resembles a USB flash drive, inside of which there is a tiny board. Despite its size, it is able to amplify the signal at a level of 16 dB. This is a stated figure, although in reality it is not true. It will be a completely useless device if the tower is located a hundred kilometers from the house. There is no gain control at all.

For the product to function, you must have a power supply with a USB connector. This device is included in the kit and there is no need to purchase it additionally. If there is a USB socket on the TV, it makes it possible to power the device from it.

The amplifier is broadband, operating at a frequency of 48.5 - 862 MHz. Supports digital TV channels. The noise level is less than 3 dB, which is considered an excellent characteristic. The output and input impedance corresponds to a value of 75 Ohms. You will not be able to connect a second TV to the device without additionally purchasing a divider. The build quality is a big question.

According to users, the main disadvantage is that some models are produced with the central wire of the coaxial output not soldered to the board. If such a situation arises, there are two options: either return the low-quality product to the seller, or disassemble the product and solder a small wire on your own. But even after performing such manipulations, the product may stop working if it is constantly removed from the USB port.

The purchase price is 550 rubles.

Remo BAS – 8102 – 01

Advantages:

• simplicity in use;
• presence of a power supply in the set;
• acceptable price;
• power supply is provided directly from the TV;
• low noise level;
• able to support a significant number of frequencies.

Flaws:

• in most cases the assembly is of poor quality;
• the plastic used is of poor quality;
• the signal gain is insufficient;
• lack of signal division capability;
• lack of signal gain adjustment.

Antex AX – S 20 U

A miniature amplifier with a different design. Wires with a specific resistance are not provided. It looks like a small box with input and output connectors on the sides. There are no difficulties with use; even amateurs have no questions. The main drawback of the product is the lack of a cable to connect the amplifier to the TV. You will have to purchase it yourself.

Despite its minimal dimensions, it is able to produce a gain of 20 dB. He copes with the assigned tasks with a bang. The noise figure is 3 dB, which is good news. An ideal purchase for those people whose apartments are located at a significant distance from the tower. It works with one TV, if there is a need to connect several more, it is worth purchasing dividers, which will negatively affect the operation of the device and can reduce its functionality to nothing.

Electricity is supplied through the use of an antenna input. In order for the product to start functioning, you need to purchase an AX-TVI USB power injector from a specialized retail outlet. This question will arise if the family does not have the latest generation TV with the ability to supply five-volt electricity to its own antenna input. Most digital set-top boxes have this functionality and are able to receive a signal in the DVB – T2 format.

The model has the ability to amplify the signal in the frequency range from 470 to 862 MHz. This suggests that you can watch digital TV in stable mode. But the device is not designed for a larger device.

The product is sold at a price of 500 rubles.

Antex AX – S 20 U

Advantages:

• build quality;
• compactness;
• presence of high gain;
• value for money;
• designed to amplify the frequency of digital TV;
• the manufacturer will equip the device with protection against voltage surges in the electrical network;
• ease of use.

Flaws:

• there is no gain adjustment;
• There are clearly not enough connectors;
• power supply is provided exclusively via the antenna cable (in a strictly established volume of 5 volts).

Remo USSH – 5 V

It is considered the most budget option. Its parameters resemble a regular adapter. Consists of two structural elements:

1. An amplifier equipped with an input for a cable that extends from the antenna. The body is made of black plastic. There is a microchip inside.
2. Elementary plastic F – white plug. Inserts into a special socket on the TV.

The elements are connected to each other with a short-length wire (up to 10 cm). It is easy to use. It is enough to connect the device to the TV, and then attach the antenna. The second action may cause some difficulties. It all comes down to different sizes of connectors. If you accidentally snag the wire, the plug will quickly jump out of the socket. This situation arises if you come across a low-quality model.

The device parameters are insignificant, but the signal amplification occurs at the proper level. Many users note an increase of 10 - 15 percent. There are no cases where the device did not produce any effect. There is an exception to the rule. It concerns the situation in which the existing antenna is already equipped with an amplifier. In this situation, the products will not function.

Broadband model. Supports frequencies in the range from 48.5 to 862 MHz. Designed for watching digital television. The manufacturer does not provide a separate connector for electricity, which is a significant drawback. Therefore, the device will only function with a TV or set-top box that is able to provide power to its own antenna connector. But the product does not need a network adapter.

You can purchase products at prices ranging from 250 to 370 rubles, depending on your region of residence.

Remo USSH – 5 V

Advantages:

• compact parameters;
• a budget option;
• stability of maintaining digital TV;
• amplification quality;
• practicality;
• simplicity in use;
• marriage practically never occurs.

Flaws:

• antenna output in one copy;
• Gain control is not provided by the manufacturer;
• The antenna cable must provide strictly 5 V power.
