Default ART vs. W8JI

No need to wait. It's easy to make the measurements
for yourself. I have already done it to prove that
standing wave current, with its unchanging phase
relative to the feedpoint current, cannot be used
to measure the phase delay through a loading coil.

If a current probe is used to measure a traveling
wave, the amplitude will be constant. If the amplitude
changes from point to point, it contains a standing wave.


Art? Measure something? You must be kidding.

Next you'll expect him to tell us how to build one of his antennas. Then
we'd all know for sure what a fraud he is.


Actually, Art gave me directions for building his 160 meter antenna, the
one people call "The Shoebox". SO you're not quite right on that point.

I looked at it, and decided that it very closely resembled an EH
antenna, with a tuned circuit on top of some coax. Those type of
antennas work after a fashion, probably through feed line radiation in
this case. So you could likely build it, install it, and make some
contacts with it. Whether that makes it a good antenna is up for
discussion. I'd probably go with something else.
