ABSTRACT:
The method of repeatably making an antenna coupler for holding a test antenna in a repeatable fixed position on the exterior surface of an aircraft or the like relative to a working antenna disposed within the aircraft. A positive mold is made of the area adjacent the antenna within the aircraft. A temporary RF shielding box is placed over the positive mold and the mold is modified to support the box repeatably in a fixed position. Pins are provided to interact with mounting holes for an antenna. A permanent box to be used as part of the coupler is mounted on the positive mold. A ribbon gasket comprising a plurality of tubular, compressible members of an RF shielding material and having mounting tabs along the length thereof is disposed against the surface of the mold about the peripheral edge. The gasket and the box are interconnected by an epoxy material, including RF shielding means. The coupler is removed from the mold and the antenna is mounted to the mounting holes. Offsetting shrinkage materials are employed in the various molding steps to minimize size deviations.
