Roy, this is the part I don't understand about some people posting on this
thread. A standing wave does *not* have a phase shift.
Robert A. Chipman agrees with you. He says the standing
wave phase is "... constant over any half wavelength ..."
Kraus also agrees. Here is a graphic from Kraus' book,
"Antennas", showing the lack of phase shift over the length
of a 1/2WL dipole. Essentially the same thing would be true
for short loaded dipoles and loaded mobile antennas.

Roy admitted some time ago that EZNEC reports that
same constant phase for current over the entire length
of a 1/2WL dipole yet he still insists that same current
can be used to measure phase-shift/delay through a coil
when it cannot even be used to measure the phase shift
through 1/2WL of wire.
