Abstract: The antenna mount is for use in mounting a GPS antenna and a differential antenna on an aircraft. The antenna mount is fixed externally of the aircraft on an outer surface of a curved rear wall of the cockpit canopy. The antenna mount comprises a shell having a top wall for mounting at least one antenna, a front wall, side walls of substantially equal length, and a rear wall. The antenna mount is sized such that electronics required by the antenna may be placed such that they are enclosed therein. The mounting bolts are provided for fixing the antenna mount to the outer surface of the rear wall of the cockpit canopy.
