An apparatus for improving the use of a transmission spectrum in a wireless communications system. The apparatus includes a first radio source for generating a first signal, a first Auto Tune Combiner for processing the first signal, a first antenna associated with a sector for transmitting the first signal, a first radio frequency test device for sampling the processed first signal and producing a first feedback signal, a second radio source for generating a second signal, a second Auto Tune Combiner for processing the second signal, a second antenna associated with the sector for transmitting the second signal, a second radio frequency test device for sampling the processed second signal and producing a second feedback signal, and a multicoupler for directing the first and second feedback signals to the first and second radio sources.
