3. Antennas
Each transceiver in a cellular phone system must have an antenna. Two
common types of antennas are used, omnidirectional and directional. An
omnidirectional antenna transmits and receives in any direction. A directional
antenna transmits and receives in a particular direction.
Fixed sites are equipped with a directional antenna because it provides the
strongest signal and can be aimed at a cellular repeater site. There are various
shapes of directional antennas, the most common being Yagi antennas, such as
the ASP962.
Mobile applications use omnidirectional antennas. Generally, an
omnidirectional antenna is a spiraled, cylindrical rod, mounted vertically. The
omni antennas listed below differ mainly in mounting hardware.
