This page covers tv channel frequencies.

Satellite tv frequency bands. The uhf band for television is the frequency spectrum between 300 to 1000 mhz. It covers the broadcast television channels 2 54 mhz to 13 216 mhz and cable tv channels 2 54 mhz to 36 300 mhz uhf band. 2 to channel no. Satellite tv broadcast frequency bands l band c band ka band ku band.

There are a number of radio frequency ranges in use in satellite communications such as c x ku ka and even ehg and v band. Tv channel frequencies are assigned in 54 to 806 mhz rf frequency band. Vhf band vhf band is the frequency spectrum between 30 and 300 mhz. These total spectrum is divided into 68 tv channels.

To prevent interference and allow for efficient use of the radio spectrum similar services are allocated in bands. The first satellite tv systems were an obsolete type now known as television receive only. The frequencies shown are for the analogue video and audio carriers the channel itself occupies several megahertz of bandwidth for example north american channel 2 occupies the spectrum from 54 to 60 mhz. The most popular frequency bands available on satellite are l band s band c band x band ku band k band and ka bands.

It includes vhf and uhf frequencies from channel no. The c band frequencies of 5 4 ghz band 5 15 to 5 35 ghz 5 47 to 5 725 ghz or 5 725 to 5 875 ghz depending on the region of the world are used for ieee 802 11a wi fi wireless computer networks. The c band alliance was an industry consortium of four large communications satellite operators in 2018 2020. Vhf band is the frequency spectrum between 30 and 300 mhz.

Modern systems signals are relayed from a communications satellite on the x band 8 12 ghz or k u band 12 18 ghz frequencies requiring only a small dish less than a meter in diameter. For example broadcasting mobile radio or navigation devices will be allocated in non overlapping ranges of frequencies. 444258 views 1054 likes.

A radio band is a small contiguous section of the radio spectrum frequencies in which channels are usually used or set aside for the same purpose. Primarily used for satellite communications for full time satellite tv networks or raw satellite feeds. It covers the broadcast television channels 2 54 mhz to 13 216 mhz and cable tv channels 2 54 mhz to 36 300 mhz.

Commonly used in areas that are subject to tropical rainfall since it is less susceptible to rainfade than ku band the original telstar satellite had a transponder operating in this.
