Claim 1
Independent Claim
215 words
A laminated antenna windshield comprising a pair of matched glass sheets, one of which has a notched portion along one of its longitudinal side edges, a metal tab smaller than said notched portion adapted to be electrically connected to a radio receiver, a plastic interlayer bonded between said sheets and a continuous length of electroconductive wire mounted in substantially symmetrical arrangement in said plastic interlayer for use as a radio antenna for said radio receiver, said metal tab being bonded to said interlayer in said notched portion, and wherein the central portion of said electroconductive wire is looped and said resulting loop located in said notched portion in spaced relation to the edge of said windshield, a solder connection enclosed within said loop as the sole means to secure said antenna wire directly to said metal tab in spaced relation to said windshield edge, wherein said metal tab has an inner end abutted against the inner end of said notched portion and a spot of solder on its upper surface, said twisted portion of said loop being in contact with the bottom surface of said metal tab and said loop being folded over said metal tab and enclosing said spot of solder on said upper surface in spaced relation to the edge of the windshield.
