Abstract
A radio paging system includes one or more transmitters (12) for sending radio signals to pagers (14) within a paging service area (10). Receivers (22) are located within the service area to receive low power transmissions from the pagers. These receivers are coupled to omnidirectional antennas (24, 26) that are disposed in pairs to form a two branch diversity antenna system. Each pair of antennas is located in a cell that forms part of a four cell cluster (66), and each pair of antennas is located on an axis (42) running through its cell. The axes are selected to provide a high and uniform level of diversity gain throughout the cluster.
