A mechanically scanned reflector antenna system that produces a compact swept diameter and overall height, which is ideally suited for use on the external surface of a high speed mobile platform where a low profile, lightweight antenna is needed. The antenna system includes a main reflector and a subreflector both formed from composite materials. A support assembly includes a pair of arms that cantilever the main reflector forwardly of a base portion of the support assembly such that a portion of the main reflector can be positioned below an upper surface of the base portion. This enables the vertical height of the swept arc of the main reflector to be reduced when the main reflector is rotated about its elevation axis. The assembly provides an even more compact system that can be enclosed within a smaller radome when the system is employed on an external surface of a high speed mobile platform.
