ABSTRACT:
A plurality of series inductors and shunt capacitors are provided between a radio transmitter and an antenna. The inductors and capacitors are arranged in binary increments and are inserted in, or withdrawn from the circuit via provided reed relays. A microprocessor activates the relays in one of several modes until the required degree of match is provided. The status of the relays is stored in provided memory such that upon tuning of the transmitter to the same channel a proper match condition can be established without resort to the matching program.
