A single cable interface for operably coupling a radio to an antenna may include a radio interface operably coupled to the radio, an antenna interface operably coupled to the antenna, and a single RF coaxial cable extending between the radio interface and the antenna interface. The radio interface and the antenna interface may each be configured to multiplex and de-multiplex multiple RF signals communicated from the radio to the antenna or from the antenna to the radio such that each of the multiple RF signals is communicated over the single RF coaxial cable. The multiple RF signals include a first RF signal and a second RF signal, the first and second RF signals having a same carrier frequency, phase and modulation type.
