Abstract
A system may include at least one antenna for receiving a first receive signal having a first signal diversity property and a second receive signal having a second signal diversity property. A first signal path may include a first frequency converter for downconverting the first receive signal to a first intermediate frequency signal having a first intermediate frequency. A second signal path may include a second frequency converter for downconverting the second receive signal to a second intermediate frequency signal having a second intermediate frequency. A transducer module may route the first receive signal to the first signal path, and route the second receive signal to the second signal path. A first N-plexer may select the first intermediate frequency signal or the second intermediate frequency signal for transmission to a cable, and to provide a data signal based on a selected intermediate frequency signal to the cable.
