When an inductor is placed in a too short standing-wave antenna to
correct its power factor, the volts, amps, and impedance at every point
on the antenna result from superposition. In general, they vary from end
to end. The impedance at any point results from a wave traveling from
the feedpoint and a reflected wave from the open-circuit at the tip of
the antenna. The reflected wave travels back toward the feedpoint. These
waves combine to produce a standing-wave pattern on the antenna much as
would be produced on a transmission line.

In a standing-wave antenna, such as Yuri has used as an example, of a
coil loaded vertical, the impedance is high and the current is
insignificant at the open-circuit antenna tip. The impedance is low and
the current is high back 90-degrees from the antenna tip.

One end of the standing-wave, coil-loaded antenna is fed by its
capacitance to the outside world. The other end is fed by its connection
to the generator. There is no inherent balance in the feed to the
antenna or a loading coil contained within the antenna.

A balanced feed to an ideal coil may result in the same current into and
out, but an unbalanced feed to a coil will likely result in different
currents in and out.

Certainly the same power in and out of a coil will produce differing
volts and amps to comply with differing impedances at the input and
output.

The extreme example comes from continuous loading. The entire antenna is
a solenoid or coil of wire. The impedance at the tip is very high. At
its feedpoint, the impedance is low. The current in the coil tapers from
one end to the other. Adding conductors to either or both ends of the
coil changes the current but does not usually eliminate current taper in
the coil.
