A system and method for managing distribution of wideband radio frequency signals includes detecting an impedance signature of a device connected at the end of transmission medium. A switch is opened to apply a wideband radio frequency signal to a transmission medium for distribution. A biasing voltage can be applied to the transmission medium based on the detected impedance signature. A signal conditioning circuit is selected based on the amplitude of the biasing voltage, and the wideband radio frequency signal is distributed to an output device.
