.~.~ With coupling network or impedance in the leadin {2}
822
.~.~.~ Impedance matching network
DEFINITION
Classification: 343/822
(under subclass 820) Subject matter wherein the passive coupling network includes one or more impedance elements constructed or proportioned to substantially eliminate the reflected wave energy between the doublet antenna and the receiver or signal energy source, caused by impedance differences.
