I'm back from Tulsa and had time to think while I was gone.
Given that none of the measurements reported so far actually
measured the phase shift through a coil, I have devised an
EZNEC example that should be very easy to duplicate for
real world measurements.

Previously I had offered a 5.89 MHz base-loaded antenna as
an example. The top of my antenna was the typical open-
circuit with its 100% reflection at the tip. W7EL took my
file and connected the top of the coil back to ground. He
changed the 'tip' of the antenna to a short-circuit to
ground so the 100% reflection at the 'tip' remained. All
that shorting the top of the coil to ground accomplished
was different phase shifts in the reflected wave. Any
information contained in the standing wave current phase
continued to be zero because of unchanging phase.

So here's the EZNEC example and an experiment that any
properly equipped person can duplicate. That includes
you and W7EL.

I took W7EL's EZNEC file and changed wire #203 from 0.25'
to 31.25'. At the 'tip' of the antenna, I installed a
439.2 ohm load that turns the antenna into a 90 degree
long *traveling-wave* antenna. Note that the current
magnitude at the top of the coil is identical to the
current magnitude through the load resistor. The load
resistor's value is very close to the calculated Z0
of the 31' #16 wire two feet above ground, using the
formula for a single wire transmission line above
ground.

I will add the supporting text to my web page later today.

Please explain the 15.68 degree phase shift through the
coil. Don't you find it strange that all the wire in the
system occupies 90.01 - 15.68 = 74.33 degrees?
