I know you aren't going to like to hear this, but your article
incorrectly claims the current difference (you call it current drop) is
related to the electrical degrees the coil replaces.
That is not accurate.

The current drop in a wire with standing waves is indeed related
to the number of degrees occupied by the wire. Why shouldn't the
same thing be true for a coil?

Consider a short vertical antenna.

Consider a 1/4WL vertical antenna. The current drop is a function
of the cosine of the number of degrees one moves away from the
source. The same thing is true for a helical antenna. The same
thing is true for a half helical - half wire antenna.

I guess it all comes down to if Barry and Yuri are right, or if nearly
every professor, scientist, and engineer from Maxwell to today are
correct. I can measure ANY antenna and prove things behave as I
described. Can you do the same?

1. You assume the unproven presuppositions of your lumped circuit
model with a religious-like fervor.

2. You make invalid measurements using standing wave current whose
phase contains no phase information. All the phase information is
known to be in the magnitude measurement, but you dismiss any of
the proven arc-cosine calculations as bogus.

With misconceptions and invalid measurements, it is no wonder that
you can prove anything in the world even when it violates the laws
of physics.
