Abstract
Apparatus and an associated method for improving the receiver portion of a radio receiver, such as the receiver portion of a radio base station operable in a cellular communication system. A mast head amplifier is provided at a mast head to amplify electrical signals formed by the mast head. The amplification level of the mast head amplifier is selected to be relatively large to more than overcome the loss and sensitivity degradation of the amplified signal when conducted therethrough to other portions of the receiver. An attenuator which exhibits a selected level of attenuation is positioned in-line between the feeder cable and the remaining portions of the receiver. The attenuation level is selected to provide a constant level of gain in a signal provided to the remaining portions of the receiver.
