ABSTRACT:
The present invention provides an apparatus and a method for mounting and both separate and selective rotational positioning of a plurality of antennas, or search devices, that are attached to the face of a tower. The preferred embodiment includes an antenna-mounting ring, or search-device mounting ring (142) that is attached to the tower (12) by a plurality of support rollers (160, 186, or 219). The antenna-mounting ring is rotationally positioned by a drive motor (214), and by a friction drive element that is connected to the drive motor and that engages the antenna-mounting ring. Preferably, one of the support rollers serves as the friction drive element.
