Over the Air antenna

Terrestrial television or broadcast television is a type of television broadcasting in which the television signal is transmitted by radio waves to the TV receiver from a terrestrial (Earth based) transmitter, a television station, and received with an antenna. The term is more common in Europe, while in North America it is referred to as broadcast television or sometimes over-the-air television (OTA). The term "terrestrial" is used to distinguish this type from the newer technologies of satellite television (direct broadcast satellite or DBS television), in which the television signal is transmitted to the receiver from an overhead satellite, and cable television, in which the signal is carried to the receiver through a cable.
