The 21-40-31 is a bicone dipole of rugged construction for airborne applications where ground plane independent operation is required.
Constructed within a glass-epoxy radome with lightweight aluminum alloy elements, this antenna provides a broad-beam +2 dBi gain elevation pattern ideally suited to data link applications on maneuverable air vehicles.
The antenna is attached to the aircraft with four 10:32 (or similar) countersunk screws and is completely sealed and foam filled for long term reliability and environmental protection.
