ELEVATION POSITIONING CRADLE FOR MICROWAVE ANTENNA

摘要

A microwave reflector antenna comprises a rotary plate that rotates about an azimuth axis. At least one elevation cradle is attached to the rotary plate to provide an elevation axis and rotates about the azimuth axis with the rotation of the rotary plate. The at least one elevation cradle has a curved guide with a plurality of ball bearings to facilitate the rotation of the reflector about the elevation axis. A reflector travels along the at least one cradle as the reflector rotates about the elevation axis. The reflector rotates about the azimuth axis with the rotation of the at least one cradle. The rotation of the reflector about the azimuth axis and about the elevation axis define a swept volume of the reflector. The at least one cradle is positioned on the rotary plate so that the at least one cradle is within the swept volume of the reflector.
