A combination antenna fixture is configured to accommodate adjustment of independent azimuths for each frequency band of operation of antennas of a mobile telephone network. The antennas may be mounted within a single radome or housing used to protect the antennas from environmental conditions. Each of the antennas may be coupled to a different movable mounting device within a radome, which may enable directing the azimuth for each antenna independently. By directing the azimuth independently for each antenna, the signal coverage area for each antenna may be customized to optimize coverage over a geographic area.
