Abstract
A dish for receiving satellite signals mounted on a stand through a casing which has a shaft projecting through the casing, the shaft having ends connected to the dish through bracket structure. Within the casing is a worm wheel mounted on the shaft. Also within the casing is a pivoted rocker plate mounting a worm gear and motor. The worm gear engages the worm wheel, and biasing means urges the rocker plate in a direction causing snug engagement of the worm gear and worm wheel. Shaft rotations are determined by electronic means.
