Glossary
Amplification coefficient
The amount of received signal amplification provided by the antenna. The higher this indicator, the more confidently the antenna will work in conditions of poor reception, the lower the signal level at which it will be ineffective. At the same time, it is worth considering that a high amplification coefficient is not a guarantee of high quality. Firstly, unscrupulous manufacturers and sellers may indicate figures in the specifications that do not correspond to real indicators. Secondly, the antenna amplifies not only the useful signal, but also various interferences, and in some cases a low amplification coefficient is preferable (for example, in dense multi-storey buildings, when the signal reaches the antenna from different directions and with different delays). And thirdly, performance above 40 dB can only be achieved using amplifiers (see below) — and amplifiers are also a source of noise, which in some situations can be quite noticeable.
VHF frequency range
The frequencies in the VHF range for which the antenna is designed. VHF includes frequencies from 30 to 300 MHz antennas with full coverage of this range are quite rare, but this is not required, because TV broadcast frequencies occupy only a part of VHF, and this part usually overlaps quite well.
Antenna sellers generally choose to sell models that are compatible with local frequencies. Therefore, in general, the frequency range is a rather specific parameter that the average user rarely needs — except when buying an antenna in another country. Also note that FM broadcasting in Europe and America uses the 87.5 – 108 MHz range, and antennas for such broadcasting (see "Signal Reception"), by definition, must cover these frequencies.

UHF frequency range
The frequencies of the UHF range for which the antenna is designed. UHF includes frequencies from 300 MHz to 3 GHz, however, frequencies above 900 MHz are practically not used in terrestrial television broadcasting, so TV antennas cover only the lower part of UHF. Also note that some manufacturers indicate a general range for their models, without dividing it into VHF (see above) and UHF; in such cases, this range is also indicated in this section.
