HHKJ2000T Transceiver represents the latest generation of VHF air-ground communication equipment designed independently by our company. Possible applications range from civil aviation air-ground communication to air traffic control system. The transceiver is an important unit in the multi-transmit and multi-receive communication command system apart from VHF filter, antenna spliter, antenna combiner, and VHF co-pole antenna.
