Light weighted antennas are used for communication
IN COMMUNICATIONS: Satellite uses satellite (orbiting) relay-stations in Space but Terrestrial uses cable or antenna-to-antenna signals based entirely on Earth to broadcast your television, radio or cell-phone :) ++++ IN ASTRONOMY: Terrestrial means Earth- (or planet-) bound; a Satellite is any natural or man-made object that orbits a planet. The Moon is a satellite of the Earth.
A satellite dish is a parabolic television antenna that receives signals from communication satellites in orbit around the earth. Its sole function is to provide the television viewer with a wider variety of channels.
A satellite antenna has one very important purpose. It is designed to allow a home to receive a satellite signal, which then allows users to receive a television signal.
Because of economics. On the ground you an afford to use a big transmitter and a big antenna, while on the satellite both have to be smaller. Therefore most of the power and the gain happens at the ground station.
An XM satellite radio antenna cannot be used as a cell phone antenna as they use a different type of connection. Satellite signals operate on a different frequency from cell phones and use different technologies in their antennas as well.

The options for car radio antennas include internal car antennas, external car antennas, power antennas, and satellite antennas. The internal antenna is the least effective and most cars come with either the external fixed antenna or the power antenna unless their is a satellite radio in the car and then it is a satellite antenna.
