ABSTRACT:
Continuity of antenna wire of an antenna windshield is determined by mounting two electroconductive receiving plates in space relationship to one another and to an electroconductive transmitting plate. The receiving plate and transmitting plate are positioned over and spaced from segments of the antenna wire. The transmitting plate is energized to form capacitors or capacitance couplings (1) between segments of the antenna wire and the plate and (2) between the receiving plates and transmitting plates. The potential difference between the receiving plates is measured to determine wire continuity.
