Southwest Antennas offers an entire line of STC flange mount antennas that can be mounted to helicopters, propeller driven aircraft, and aerostats for air-to-ground communication.

These antennas feature a wide mounting base with pre-tapped screw holes, providing a secure way to mount the antenna to the aircraft. Lockwired screws further enhance the safety of these antennas by ensuring that the screws can't back themselves out due to vibrations from the airframe.
