I say that the phase relation MUST be the same everywhere on the coil.

That does not seem to me to support Cecil's proposition at all, I
understand Cecil to argue that there is a substantial phase change in the
coil current along the coil.

Please understand exactly what I am saying, Owen.

1. There is a *substantial* phase change in the *traveling-wave*
current along the coil. Traveling-wave current is hard to
measure in a standing-wave antenna but its phase yields
complete and accurate phase/delay information.

2. There is virtually *no* phase change in the *standing-wave*
current along the coil. Standing-wave current is easy to
measure in a standing-wave antenna but its phase yields
close to *zero phase/delay information*.

3. In a standing-wave antenna, the total current is primarily
standing-wave current. In a loaded mobile antenna, the standing-
wave current is approximately 90% of the total current thus
tending to mask the traveling-wave current.

W8JI's and W7EL's "measurements" were made using standing-
wave current. They should have instead used traveling-wave
current. It's an easy mistake to make but one would think,
after five years, it is time to admit the mistake.
