Abstract
A wireless PBX system utilizes base stations dispersed throughout an area to be served with wireless telephone service. The base stations utilize multiple antennae to reduce problems associated with fading and multipath. In the present invention, the antennae of a base station or similar apparatus are rotatable, at least in pairs, so that the base station may be hung vertically, horizontally, or at some other angle to the horizon and the antennae may be readily oriented to a position which provides for preferred propagation characteristics for the antennae for the local area in which the base station is mounted.
