Avionic Crossband Repeater

X-Band Air

Bridging the Gap Between Air and Land
Communication just got easier with Icom’s X-Band Air repeater. The X-Band Air provides seamless inter-band communications between VHF or UHF frequencies and air band frequencies. This provides interoperability between ground crew and aircrew for forestry, hospitals, and oil rigs. The repeater also has full VFO capability in one box.
