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 ...
FM channel 200, 87.9 MHz, overlaps TV 6. This is used only by K200AA.; TV 6 analog audio can be heard on FM 87.75 on most broadcast radio receivers as well as on a European TV tuned to channel E4A or channel IC, but at lower volume than wideband FM broadcast stations, because of the lower deviation.
Class R: VHF, 100 kW low-band (channels 2–6), 325 kW high-band. (channels 7-13) Class S: VHF, more than 100 kW low-band/325 kW high-band. Notes: Official definitions of these classes are difficult to locate. The values above are inferred from the Industry Canada database. There is some ambiguity about the difference between Classes C and D.
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 .
A television channel, or TV channel, is a terrestrial frequency or virtual number over which a television station or television network is distributed. For example, in North America , channel 2 refers to the terrestrial or cable band of 54 to 60 MHz , with carrier frequencies of 55.25 MHz for NTSC analog video ( VSB ) and 59.75 MHz for analog ...
