I don't know much about these antennas but I have a friend in Colorado who
has one and we often talk on 20 or 40 meters. He has only 100 watts output
and he puts a strong signal into Alabama. It certainly seems to work for
him. I have a Carolina Windom and I believe his Isotron performs better
than my windom.

I've been seeing pictures of these weird antennas for years. Near as I
can
tell from the picture, it's essentially a heavily-loaded very short dipole
with two large capacity hats at the ends. But it's impossible to tell
from
the pictures what the exact configuration is. Can anyone tell me exactly
what's happening? Is the mast part of the radiating system? The
feedline?
The literature (including the manuals) sort of implies that it is.

Also, from the pictures, I get the impression that the standard mast-mount
configuration is mostly vertically polarized. This would certainly
account
for reports I have read that the antenna is a bit of a dud at short range
on 80m.

If someone has a computer model for it for MMHAMSOFT's modeller, that
would
be GREAT!

The reason I'm asking is that I'm in the process of trying to design
something really low profile for a second floor apartment balcony for 75
and 80m.
