Default Current across the antenna loading coil - from scratch

What we are saying that the loading coil appears to replace "missing"
electrical degrees of the radiator in order to make it resonant, ...


W8JI says we are correcting the power factor. Every EE knows that
correcting the power factor involves shifting the phase, i.e.
the coil cannot correct the power factor without providing a phase
shift.

The whole controversy is that "gurus" claim current doesn't drop across the
coil, while we say that it does, ...


That context is specifically inductively loaded mobile antennas
where the current decreases from source to tip of the antenna,
true for all electrical 1/4WL monopoles.

For other antennas, the current may DROP, the current may RISE,
or the current may STAY THE SAME magnitude depending upon where
the coil is installed in the standing wave system. In particular,
none of the "gurus" has even attempted to explain the RISE IN
CURRENT through the coil in the right hand system at:

There have been about 10 examples proving the "gurus" wrong and
they simply chose to ignore those examples. They complain that
those examples are biased toward technical correctness. I say,
YES, THEY ARE. AREN'T THEY SUPPOSED TO BE TECHNICALLY CORRECT?
