An architecture and protocol enables signal communications between either a frequency translation module and a decoder within a dwelling, or between an antenna and a decoder within a dwelling. According to an exemplary embodiment, the decoder comprises a switch 33 between the low noise block converter power supply, and a transceiver and output coupling. The switch 33 generates a high impedance during operation of the frequency translation module and the LNB power supply 38, thereby isolating the transceiver and the output coupling from the LNB power supply. The switch generates a low impedance between the LNB power supply and the transceiver and output coupling during operation of the LNB power supply.
