1. A communications system comprising:
radio frequency (RF) circuitry, an antenna assembly, and an RF cable coupling the RF circuitry and the antenna assembly;
the antenna assembly comprising an antenna and RF impedance selection circuitry coupled thereto;
the RF circuitry configured to
communicate RF signals with the antenna via the RF cable, and
communicate RF impedance selection signals to the RF impedance selection circuitry via the RF cable and using an alternating pulse width modulation scheme.
