The AT-903/G is a directional antenna that consists of a modified dipole probe mounted in a ridge-loaded horn that can be positioned for either vertical or horizontal polarization. It has a broad frequency response and is capable of operation throughout the entire frequency range without adjustment. It is installed on top of Mast Extension Kit MK-806/GRC and Mast AB-577/GRC. Connections to the receiver and transmitter are made through a coaxial cable to the front panel connector on the transmitter.
