Reduced aircraft VHF communication antennas using multi-channel VHF radios

摘要

A multichannel two antenna radio unit device comprising a left very high frequency (VHF) radio and a right VHF radio is provided. The left VHF radio unit comprises a left VHF radio transceiver, the left VHF radio transceiver comprising a left wideband multi-channel receiver configured to receive voice channels and data channels in an aeronautical VHF communication band, the left VHF radio configured to communicate on at least two voice channels and at least one data channel. The right VHF radio comprises a right VHF radio transceiver, the right VHF radio transceiver comprising a right wideband multi-channel receiver configured to receive voice channels and data channels in an aeronautical VHF communication band, the right VHF radio configured to communicate on the at least two voice channels and the at least one data channel, and communicatively coupled to the left VHF radio unit via a bi-directional serial bus.
