Cecil,

I have sent the files to you, as requested. The resonant whip ended up
at about 10 feet, not 8, because I tired of the continuing the
optimization. The phase shift found from the traveling wave version was
about 7 degrees. The coil was similar to the coil you have been using,
except squeezed down to 6 inches tall, 4 TPI. You can refine the models
or perform the required adjustments as you wish to get the 8 foot
version. I would not expect radical changes, but who knows?

It is always possible that I made a mistake in the modeling. If so, I am
confident the entire world will know in short order. 8-)

Here's what you guys need to do to convince me that you are
right.

1. Develop a coil acceptable to EZNEC that resonates an 8
foot whip on 4 MHz over mininec ground. Send me a copy of
the EZNEC file.

2. Put the same coil in the traveling wave environment as
I have done at: http://www.qsl.net/w5dxp/test316y.GIF
and report the phase shift through the coil. Send me a
copy of the EZNEC file.

If you are so right and I am so wrong, that shouldn't be
too difficult for half a dozen gurus (including the
developer of EZNEC).
