Default Isotron antennas

I've been looking for an EZNEC model of the Isotron for the past 6
months, Dave. I haven't found anybody who has modeled one. I understand
the Isotron is "lossy" and "nothing but radiating feedline" but it
would still be interesting to see it on a grid or check the numbers in
NEC. And - just like every antenna, you'll find people who use these
things and love them, proving that "the best antenna is one that works
for you". I've got to agree with what others are telling you. A small
loop is the best performing antenna I've been able to find for my very
challenging antenna environment. Other than the small bandwidth, I know
it's working better than any inverted-vee or shortened dipole I've ever
been able to get up amid the power lines and CATV cables here.

Good luck.

I actually have a fairly good ground--a balcony rail that forms an
aluminum grid about 40 feet in length and 3 feet in height. That's bound
to have a decent capacative coupling to real ground inside the building,
even if the rails are bolted into wood.
