Common Television, Satellite and Earth Station Terms
A satellite is a sophisticated electronics communications system that orbits in space at the same speed as Earth. Satellite dishes are installed near homes in order for households to receive a plethora of channels. TVs receive cable channels from all over the country that they wouldn't normally be able to watch. Professional technicians will need to be called in to install these dishes and connect them to television systems. In addition to cable TV, radio stations are also transmitted to vehicles. Users typically must pay a fee with satellite radio, but don't have to listen to the typical amount of commercials and advertisements.

Earth Station - An Earth station is a term used to describe the equipment necessary to receive a signal that is transmitted from a satellite. This equipment includes receiver, antenna, low-noise amplifier and down-converter.
Polar Mount - A polar mount is a mechanism that steers the elevation of an antenna on a single axis.
