LOW PROFILE/FLANGE MOUNT/BNC
The DM N43-1, DM N43-3, and DM N43-4 are low silhouette antennas for use with 75 MHz marker beacon receivers. When properly mounted on the underside of an aircraft, the antennas provide a broad, single-lobed pattern directed downward. The radiation is polarized parallel to the long dimension of the antenna. Electrical elements of the antenna are completely sealed by foamed-inplace resin within a plastic housing. As a result, the DM N43-1 is rugged enough for use on all subsonic aircraft.
