Abstract
The present invention provides an apparatus and a method for mounting and both separate and selective rotational positioning of a plurality of separate antennas, or search devices, on a single tower. Three of the preferred embodiments for use in mounting and rotationally positioning antennas or search devices include an antenna-mounting ring, or search-device mounting ring (142, 292, or 406) that is attached to the tower (12) by a plurality of support rollers (160, 219, or 306). The support rollers are operatively attached to the tower or to the antenna-mounting ring and supportingly engage a circumferential groove (150, 298, or 430) which is located in either the antenna-mounting ring, or in a tower-attaching ring (402) that is interposed between the antenna-mounting ring and the tower. The preferred embodiment for use in mounting of antennas of the type that are rotationally positioned and then permanently left in that rotational position utilizes two vertically-spaced and arcuately-shaped mounting portions (42a and 42b).
