CM-HT12/VHF Heliport Radio Receiver
Our L-854 FM radio receiver/decoder is designed to provide pilots with direct, unassisted air-to-ground control of airfield lighting systems. This field tunable radio allows pilots to activate airfield lighting with a series of 3,5, or 7 microphone clicks in a 5-second period. An integrated selectable timer shuts airfield lights off after 1, 15, 30, or 60 minutes of illumination. Our L-854 receiver is particularly useful for small to mid-sized airfields where continuous nighttime illumination is unnecessary and expensive. The unit is a virtual necessity for remote sites where the volume of qualified on-site control personnel may be limited. Our rugged, solid-state design will provide years of service and is the perfect replacement for aging “crystal” based units.
