ABSTRACT:
A method and apparatus for rotating an antenna, including a keypad is used to first program a controller for storing a plurality of individually selectable positions for the antenna, a particular key of the keypad representing a programmed position for the antenna, whereafter programming the keys of the keypad are individually depressed for commanding the controller to operate a motor driven rotator for moving the antenna in a clockwise or counterclockwise direction to the position associated with the momentarily depressed key. Also, visual indicators are arranged in a compass configuration for indicating the positioning of the antenna as it rotates, and selectively indicating the rest position of the antenna.
