ABSTRACT:
Disclosed is a dynamic antenna tuning system which may be employed with a high powered transmitter and a very narrow band antenna. An input signal may be applied to the transmitter so as to frequency modulate the transmitter. A unique and compact tuner circuit is connected in series with the antenna whereby inductance changes therefor can be varied by a predetermined amount by means of a plurality of discrete inductances to be selectively switched into the resonant circuit to produce a desired change in the resonant frequency of the antenna sufficient to compensate for deviations in the operating frequency of the transmitter.
