Abstract
A communications headset having an antenna on each earpiece and having an RF switch for determining which antenna is receiving the superior signal and selecting that signal for amplification and distribution to headset speakers. A cable, supported and secured to a headband of the headset, connects the two earpieces for signal and power transfer. An illustrated embodiment has a transceiver and a speaker in an earpiece, with the RF switch, switching logic, and audio processor in one earpiece. Other configurations are within the scope of the invention. The RF switch selects the superior signal responsive to signal strength, signal to noise ratio, and/or similar figures of merit. Monitoring for signal superiority is at a high bandwidth to prevent granularity in the switching becoming noticeable to the user. The antenna corresponding to the superior signal is also used for transmitting from the headset.
