ABSTRACT:
A base support for a moveable antenna. The base support is attached to an upstanding mounting member and the antenna is attached to a support structure connected to a base member. The support structure is operatively connected to a worm gear assembly which includes a motor driven worm and worm gear disposed between the base member and support structure to effect movement of the antenna about a predetermined axis. The motor driven worm is supported at an outboard end by a first bearing assembly and supported at its opposite end by a pair of spaced apart bearing assemblies to prevent backlash between the motor driven worm and worm gear. A second worm gear assembly including a similarly supported motor driven worn and worm gear can be interposed transversely between the first support structure and a second support structure to effect movement of the antenna about a horizontal axis.
