The AS-309 is a linear polarization sector antenna, especially interesting for camera links. It works in 3GHz band. This antenna is commonly used in the receiver site. Its 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.
This antenna offers a wide coverage area with 9dBi gain; it has 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 re-steer the receiver antenna.
