David and others,
Would you be so kind to point me to the review(s) on e-ham. I can find very
little about this antenna despite searching on the term "Pan Cake-Antenna" on
eham and google. It seem I'm the only one that isn't familiar with the
antenna. I did download N3OX's EZNEC model so I understand what it is.
Here are some links to another spiral loaded vertical type antenna. It's
implementation is only single band.

Ralph wrote a much more user friendly article for antennex.com with pictures.
I modified the antenna in the antennex.com article from vertical to a dipole
and was quite pleased with it. I used it when our family moved to a condo
while our house was remodelled. However, it was only single band (40m in my
case). I have some pictures somewhere, I'll see if I can find them.
