Abstract
Abstract Method of and means for improving the receptive qualities of a window- or windshield-mounted antenna of an automotive vehicle, by providing a closed annular conductive screen extending about, exteriorly of, adjacent, and in fixed relation with the antenna secured to the surface of a window or windshield, and in grounding such screen from a point thereof to a selected point of the vehicle or the coaxial cable lead-in from antenna to receiver.
