ABSTRACT:
A base support for supporting, positioning and securely maintaining a desired position of a communications dish antenna includes a non-rotatable worm gear having radially outwardly extending teeth and a motor driven worm having a continuous helical tooth intermeshed with adjacent ones of the worm gear teeth. In order to prevent backlash between the gears should any of the gear teeth become worn, damaged or otherwise deteriorated, the worm is pivotally mounted with respect to the worm gear and a force means such as a spring continuously urges the worm toward the worm gear to maintain tight intermeshing engagement. Thus, in the event of uneven or intermittent gear tooth deterioration, the communications dish antenna will be maintained securely in a desired position. Also, the support permits 360.degree. movement of the antenna around the base support and the pivotal mounting of the worm alleviates jamming of the gears.
