ABSTRACT:
A satellite antenna drive mechanism which includes a drive gear housing for reciprocally driving a satellite antenna dish. Generally, the satellite dish is supplied with a retaining bracket to which a U-shaped bow screw is mounted. The bow screw threadably engages the drive gear housing such that rotation of the drive gears causes a corresponding movement of the bow screw and the dish. The drive housing includes three meshed gears which cooperate to drive the bow screw. A first gear drive is connected to drive means for manually or mechanically driving the gears. An intermediate gear connects the first gear to a third internally threaded gear which receives the bow screw of the antenna dish. This third gear drive is positionally captured between the wall plates of the housing yet is free floating within the housing to provide smooth travel of the bow screw through the drive housing.
