Default Current through coils

Richard, lest you get nit-picked to death again, let's be clear
that you are talking about a standing-wave r-f environment.

If a coil is installed in a traveling-wave r-f environment, with
no standing waves, the magnitude of the current through the
coil will be the same at both ends, minus losses.

It's the phasor sum of the forward and reflected current phasors
that causes such a large variation in coil current in a standing-
wave r-f environment illustrated by the graphic at:

Wonder why none of those resident gurus have bothered to
explain the current distribution in that coil? Have you noticed
my questions about the technical references that I have
provided just keeps piling up with no responses?
