Antenna tv

In telecommunications, a television antenna or TV antenna is a particular type of antenna specializing in the reception of the radio signal of the terrestrial, analog or digital television, whether it is emitted from the broadcasting stations. In Europe these signals are radio frequency signals within the 50-85 MHz band, ie the frequencies in the range of Very High Frequency (VHF) and Ultra High Frequency (UHF). To cover this wide bandwidth, television antennas are broadband antennas made up of multiple conductors of different length, corresponding to the specific frequencies to be captured (log-periodic antenna). Generally, the antenna elements must be half the length of the signal wavelength they are to receive (dipole antenna). The advent of digital television does not involve changes to the receiving antenna. #antenna_tv #tv
