Look back at Roy's reply on how to implement this in a
model. The way he suggested would appear to have the source driving
the 1/4 wave ground wire as an end fed element.

Is it possible for you to publish a graphic of your
antenna system or share your EZNEC file? I'm not sure
that anyone really understands your text description.

Cecil,

I sent you am e-mail with the EZNEC file attached. Don't know how to
make it public here.

Thanks for looking at the file for me.

Do you mind if I upload it to my web page so
everyone can take a look?

OK, Dykes, anyone interested in downloading your
EZNEC file can do so from:

http://www.w5dxp.com/ocfv.EZ

Roy, w7el, offered to help. Did you send your .EZ
file to him by email?

Thanks for making the file public Cecil. I'll send a copy to Roy. He
said he would be tied up with field day activities through the
weekend.

I had a look at your model and couldn't make head and tail of it.

Here is a simple model of a Carolina Windom, well to the extent that it
can be guessed from the smoke and mirrors used to describe and promote
it... http://www.vk1od.net/files/CW01.EZ .

The model attempts to represent a voltage balun at the dipole feed point,
a vertical coax feedline to a common mode choke (2000+j2000) and then the
coax outer is grounded via a moderately good station ground (directly
under the feedpoint). The power lost in the ground connection and the
choke can be found from the reports. The model does not attempt to
represent the differential mode transmission line, though it could be
done. The CW's voltage balun at the feedpoint is modelled as a pair of
equal voltage sources, with the common mode path connected between them.
I have treated the voltage balun as having zero common mode impedance, it
is probably a few ohms, but insignificant in this model.

As Roy I think already advised you, you have to model the entire common
mode path to ground and my example above is a simple one, but it
demonstrates a technique.

You will see the currents flowing in the three conductors (each side of
the dipole and the coax outer), and their contribution to / effect on the
pattern.

Others may disagree with my representation of the Carolina Windom.
