Abstract: An antenna deployment system, for use in mounting an antenna assembly to a vehicle having a vertical surface. The deployment system is housed within a cabinet having sides, a rear, a bottom, an open top, an open front, and cabinet doors which selectively close the cabinet front. A platform is hingeably mounted to the cabinet rear and is capable of entering a deployed horizontal position wherein the platform extends across the open top for allowing the antenna assembly itself to enter an operative position, and a stowed vertical position wherein the antenna assembly is parked against the platform and wherein the antenna assembly is retracted safely within the cabinet and is closed therein by the cabinet doors.
