Satellite Television

Geo stationary satellites are satellites that are positioned about 36,500 kilometers or 22,300 above the Earth's equator, in a region called the Clarke's belt and rotate at the same speed as the Earth and hence appear stationary to an observer on the Earth. Satellite television receives TV signals that are beamed from the Earth and reflected from these satellites on to a TV dish. These orbiting satellites have capacity to carry several hundred TV channels through their transponders and enable a viewer to receive them anywhere on the Earth.

These transponders operate in various signal bands like C band, Ka band, Ku band etc. These bands are comparable to VHF, UHF etc. frequency bands of radio signals.
