An antenna for a base station comprising a plurality of antenna arrays (40; FIG. 6a) each capable of forming a multiplicity of separate overlapping narrow beams in azimuth, the arrays being positioned such that the beams formed by the arrays provide a coverage in azimuth wider than each array. Means for receiving r.f. signals for a given call include a plurality of receive amplifiers (62; FIG. 6a) one for each beam of an antenna array, means for combining the outputs of the plurality of receive amplifiers, switching means for applying the combined receive signals to the r.f. transceiver handling the given call; and a single power amplifier (52; FIG. 6a) for transmitting r.f. signals for the given call for applying the transceiver transmit signal to an individual one of the beams.
