If a Texas Bugcatcher Coil could be turned into a
traveling wave device instead of a standing wave
device, the inherent phase shift through the coil
would become obvious. I used the Helix option in
EZNEC to generate a reasonably close model of a
75m Texas Bugcatcher coil and loaded it with a
resistance equal to the coil's characteristic impedance
which essentially eliminated the reflected current,
leaving the forward current intact and visible. All
of the data points on the following web page came from
EZNEC. All of the files are available for downloading.
Please take a look at:

Soooo, W8JI and his worshippers were right! Current is just about constant
through the loading coil (for traveling wave) but they did not know the
case, in which this happens in the antenna circuit, while they were sticking
with DC circuit analysis.
I hope Roy approves your use of EZNEC for this demonstration and perhaps
will admit that they were wrong, and indeed the RF current through standing
wave antenna circuit, such a quarter wave resonant vertical monopole, the
loading coil has the current drop along the coil (standing wave circuit).

This exercise, and Walt's, and whole commotion of reflections and
interference has open my antenna eyes a bit wider and allow me to understand
better wasaaaap in antenna circuits, which should lead to mo' betta' antenna
designs.
The only problem I have swallowing Gaussian soup, to understand how on earth
and 100 years of antenna tinkering could not see the magic of this
(another) miraculous way of getting much more and better signals out of
antenna with given power.

Thanks guys, this is the best antenna NG, allowing good and questionable
posts and free discussion, unlike the TowerTalk antenna reflector where any
"heresy" against W8JI crapola "teachings" gets suspended.
