standing waves, because the positions of the maxima and minima stay in
the same places and don't move.

Roy, since you understand the above, you must also
understand that the mostly unchanging phase of that
standing wave current (relative to the source current)
cannot be used to predict the delay through a wire or
a loading coil.

How about correcting your previous postings on that
subject? Your reports of unmeasurable phase shift
through loading coils are supported by EZNEC and
are completely meaningless as far as predicting
the delay through a loading coil or even through
a wire.
