The AV-64 is a boat type marker beacon antenna designed for very low drag. It is constructed of an acrylonitrite-styrene-acrylic (ASA) shell with the internal parts encapsulated in rigid urethane foam for mechanical and electrical stability. The white color allows for maximum performance without losses due to color pigments or unseen dirt. The antenna is supplied with cellular neoprene mounting pad and hardware. The antenna is designed to operate at speeds up to 350 mph and altitudes up to 50,000 ft. It has a drag force of 0.22 lbs @ 250 mph. This antenna is a direct replacement for Comant's model CI-102.
