RAMI AV-74 Blade Style Transponder or DME Antenna

Note: Most glider pilots prefer the AV-74-1 below because the longer mounting studs make it easier to mount through a sailplane fuselage.

The AV-74 is a broadband blade type antenna for transponder or DME application. The antenna housing is constructed of an acrylonitrile-styrene-acrylic (ASA) shell. The white color allows 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 0.09 lbs @ 250 mph. This antenna is a direct replacement for Comant's model CI-105.

Length of Mounting Studs: 10 mm (0.375 in)
