The AS-209 and AS-309 are a linear polarization sector antenna, especially interesting for camera links. They work in 2 GHz (AS-209) and 3 GHz (AS-309) band. These antennas are commonly used in the receiver site. Their low weight and the N male connector make possible the direct connection to the down-converter, no cables are needed and cable losses in the receiver site are minimized.
These antennas offer a wide coverage area with 9dBi gain; they have a 80º horizontal beamwidth and 80º vertical beamwidth. This wide radiation pattern makes possible that the transmitter moves freely in the coverage area with no need to steer the receiver antenna.
