Unless you can prove you are omniscient, Ian, the problem could
possibly be with your misunderstanding of something, not mine.

My EZNEC data posting proves that EZNEC correctly predicts the
differences in the traveling wave current and the standing wave
current. I'm building a new web page around those results. I have
graphed the EZNEC results and they are available at:

Please note that the traveling wave magnitude looks like the
standing wave phase and the traveling wave phase looks like the
standing wave magnitude. Anyone who maintains that there is no
difference between a traveling wave current and a standing wave
current should take a long close look.

The corresponding EZNEC files are available at:
