The output power of a TV transmitter is the electric power applied to antenna system. There are two definitions: nominal (or peak) and thermal.Analogue television systems put about 70% to 90% of the transmitters power into the sync pulses.
Stations on band III (channels 7 to 13) can go up by 5dB to 316 kW video, 31.6 kW audio, or 160 kW digital. Low-VHF stations are often subject to long-distance reception just as with FM. There are no stations on Channel 1. UHF, by comparison, has a much shorter wavelength, and thus requires a shorter antenna, but also higher power. North ...
