ABSTRACT:
An antenna matching network for matching a citizens band radio transceiver to a standard automotive whip or windshield antenna utilizes a matching section for matching the nominal 50 ohm output of the citizens band transceiver to the generally lower impedance of the automotive antenna. A trap tuned to the citizens band prevents the output of the citizens band transmitter from damaging the automotive broadcast receiver when transmitting. The matching section is tunable over a sufficient range to match the citizens band transceiver to most automotive antennas, and a dual sensitivity indicator is utilized to aid the operator in tuning the matching network to provide optimum matching without the use of specialized equipment.
