Abstract: A mounting bracket for mounting a Global Positioning Antenna to the fusel of a fixed wing aircraft. The apparatus comprises a rectangular shaped mounting plate having a cylindrical shaped member positioned in the center of the mounting plate and extending from its bottom surface. There is an aperture extending through the cylindrical shaped member and the plate through which the antenna cable passes with the cable connecting the antenna to the receiver. The antenna mounting bracket is secured to the aircraft by inserting the cylindrical shaped member into the sextant port of the airframe so that the bottom portion of the cylindrical shaped member including a pinning aperture extends into the interior the aircraft. A quick release pin is inserted in the pinning aperture to tightly secure the antenna to the airframe.
