Abstract: Apparatus for rotating an antenna to a predetermined position and maintaining said position is disclosed. The system comprises an antenna position sensing signal source, a desired position signal source, both of which provide analog signals, position comparator means, and antenna drive means. Comparison of the desired position signal and actual position signal generates a direction relay signal and an antenna rotor drive relay signal which together activate the antenna rotor drive means for rotation in the proper direction to the desired position. Circuitry is included for automatic operation in conjunction with equipment utilizing predetermined channels, such as a radio or television receiver, and for manual override or testing and calibration of the automatic operation.
