Here is a list of TV frequencies. In the US, a TV channel is a 6 MHz wide chunk of bandspace. The bottom edge of the over-the-air channel 2 is 54 MHz and the upper edge is 60 MHz. Within this 6 MHz space is a video carrier, a color carrier, and an audio carrier.
Nomenclature of the frequency and wavelength bands used in telecommunications. (1953-1956-1959-1963-1966-1974-1978-1982-1986-1993-2000-2015) Scope. This text recommends the use of the hertz (Hz) as the unit of frequency, and the nomenclature to be used for the description of frequency and wavelength bands.
The whole frequency range, from a few kHz up to around 2.5 GHz is used for an enormous variety of services, including sound broadcasting and television, commercial, professional, government and military communications of all kinds, telemetry and telecontrol, radio telex and facsimile and amateur radio. There are specialized applications,
This chart shows CATV and broadcast channels used in the United States. The frequency relationship to the harmonics of HF, VHF and UHF amateur bands can be readily seen. This will help identify those channels that are harmonically related to the transmit frequency.
The purpose of this Guide is to provide information for improving UHF television reception in the home. The Federal Communications Commission originally allocated twelve channels for television broadcasting. These channels, numbers 2 through 13, are in the "very high frequency" or VHF band. (Originally Channel 1 was also
Ultra high frequencies (UHF) are those that are located in the band from 300 MHz up to 3 GHz. This frequency band is very effective for wireless microwave links, constructions of cellular systems (fixed and mobile), mobile–satellite communication channels, medium range radars, and other applications.
