 Bellows AFS was also the Air Force transmitter facility site for long haul HF (High Frequency) radio communications from the late 1950s until HF radio was largely replaced by the military satellite program.HF radio links were established using highly directional Sloping "V" antennas to Clark Air Base, Philippines, and McClellan AFB, California.Message circuits were originated or relayed at Hickam AFB, near Pearl Harbor, and sent to Bellows for re-transmission over the HF systems.
