If someone has a computer model for it for MMHAMSOFT's modeller, that

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.

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.
