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.


Honestly, Cecil, it's pretty hard to know what you mean considering
the reckless way you throw around the term 'phase'. I'll grant that
you might know what you mean, but I don't see how you can expect
anyone else to.
