Yea that's what I was expecting you to say. I can remember seeing
descriptions of this "as if the ground plane is folded down around the coax"

I think I might try this ;-)

Thanks again all!

I don't understand how this would work.

Now that you mention it, neither do I. I just copied it from
the 1993 ARRL Handbook, Fig. 3, on page 14-4. I do know how it
works when feeding a balanced antenna. Let me redraw it with
one that I know works.
