The need for decoupling a vertical antenna from its coaxial feedline can be
appreciated by referring to Figure 1. Antennas which are driven by 2-
conductor transmission lines always have two terminals, insulated from each
other, between which the high frequency AC voltage generated by the
transmitter is impressed. Figure 1 shows a typical center driven dipole
antenna, with terminals a-b, across which the AC voltage generated by the
transmitter is connected. During eac
