5 best antenna amplifiers
Antenna amplifier is one of the most important elements of the broadcasting system, which is necessary to improve the signal quality at a considerable distance from the broadcasting repeater or in case of unstable communication with the satellite. Has a directional effect on changing the frequency of the received antenna wave with subsequent transmission to the appropriate equipment. In addition, these devices can perform an additional function of a splitter - splitting the signal into several streams to display the picture on different TV screens.
The range of amplifiers on the market is not so popular with eminent manufacturers, and, therefore, does not have a huge number of models sold. However, the whole problem with choosing a good device rests on an elementary ignorance of the main criteria, which is why purchases are very often in vain. Therefore, having carefully researched this segment, we have compiled for you a rating of the best amplifiers for digital and analog television, which are very popular among domestic users.
TOP 5 best amplifiers for antennas
5 DVB-T2 amplifier
A digital signal amplifier of the DVB-2T standard, despite its dubious origin, has good performance. Firstly, the method of execution attracts attention: the microcircuit of the device is placed in a sealed steel case, which reliably protects it from mechanical stress. True, the amplifier should still be protected from atmospheric precipitation, since its location should be as close as possible to the terrestrial antenna itself.
Secondly, the purely operating parameters turned out to be at the same level. The gain in this model varies within 20-23 dB, and the noise level does not exceed 2-3 dB. The only caveat noted in many consumer reviews: it only supports frequencies from 470 to 900 MHz, thus being ideal only for installation in a country house or in a private house outside the city.
4 Locus LA-31
An amplifier for indoor and satellite antennas of a single-stream type, designed to stabilize and improve the quality of signals in the range from 1 to 69 channels. It is distinguished by its amazing survivability against the background of level (by price) competitors, which is often reported by users in their thematic reviews. Having, in general, good operational parameters, when connected, the amplifier manifests itself a little unstable, not all the same it does not go beyond the designated working limits. The gain in this case is from 10 to 22 dB, varying in a chaotic manner across the entire group of supported channels.
Locus LA-31 is installed in the break of the drop cable (standard circuit), and as close as possible to the antenna output. Subject to the main operating conditions (namely, protection from atmospheric precipitation), it can serve for a long time. An excellent device for budgetary increase in signal quality in the country.
3 Rexant 05-6202
The main purpose of the Rexant 05-6202 is to separate signals into streams, however, to work in this mode, the device simply needs to amplify the transmitted frequencies. The main advantage of this device comes down to its versatility: while supporting the perception of a large frequency range (from 5 to 2500 MHz), it is capable of working with terrestrial, cable, and even digital television.
Among the advantages of this splitter, consumers also include a design parameter: while analogs have a maximum of two connectors for a cable, Rexant 05-6202 has three F-type outputs at once, allowing a signal to be fed to three sources. Of course, for such a wide functionality (and low cost), we had to pay with reliability: during operation, one of the branches of the splitter may simply fail.
2 Eurosky SWA-105
The Eurosky SWA-105 is the only integrated amplifier in the rating capable of operating in the 174-862 MHz frequency band. In other words, its capabilities apply to both cable and terrestrial (digital) television, and therefore it can be used both within the city and in dachas with private houses. The gain here is an impressive 25 dB, while the noise floor does not exceed the threshold of 1.7 dB.
In the accompanying materials, the manufacturer also did not forget to mention the comfortable temperature range at which the circuit is able to function normally. It ranges from -40 to +50 degrees Celsius, which was made possible due to the absence of a case. Judging by user reviews, high-quality signal amplification is observed at a distance of 80 kilometers from the repeater, which is also a decent result.
1 Alcad AL-200
A high-quality TV signal amplifier designed for fine adjustment of the centimeter and decimeter wavelength ranges. It performs equally well in cable (indoor antennas) and terrestrial (digital and satellite antennas) television networks, demonstrating the ability to amplify frequencies from 40 to 318 and from 470 to 862 MHz. Despite this, in cable broadcasting, it can allow a decrease in the amplification efficiency, up to a complete lack of efficiency (with a frequency variation of 318-470 MHz).
The gain of Alcad AL-200 in the indicated ranges is 14 and 24 dB, respectively, and the noise figure does not exceed 4.5 dB. A nice bonus to the functionality is the ability to split the signal into two streams in order to broadcast the picture to several TVs at once. Despite the high cost, this amplifier is the most popular in Russia, mainly for its outstanding quality and performance parameters.
