Abstract: The preferred embodiment of the present invention is a communications apparatus which includes a first transmitting antenna array (15A) having a transmitting antenna (16) which is dedicated to serve only a first sector (12). Similarly, a second transmitting antenna array (17A) having a transmitting antenna (18) is dedicated to serve only a second sector (14). Each of the transmitting antenna arrays (15A, 17A) have a beamwidth (19) of generally less than fifteen degrees. Both the first and the second transmitting antenna arrays (15A, 17A) emanate shaped beams which are alternately polarized to ensure the isolation of beams that serve adjacent sectors.
