THAT was also quoted in the same article I stated. But would think a
mobile antenna (this on second floor apt.), and a tripod mount, with
radials for a counterpoise over a balcony (at night) would be much more
effective than this dawg! think mfj or another outfit has the setup for
this --- (maybe Outbacker, and that NOT that great)! Jim nn7k

A small one-turn loop is hard to beat.

Yes, more effective than the Isotron but disappointing, nevertheless
(been there done that). A balcony-mounted mobile screwdriver is still
pretty far down from a properly designed small loop on 75m. However,
a vertical longer than a mobile screwdriver would be something worth
considering. I think HighSierra has one of those.

Actually, I *am* thinking outbacker or MFJ. The balcony is large and
aluminum-railed, which should actually form a decent counterpoise if it
doesn't blast my sat. TV and 2m stuff all to heck.

I just wondered what the theory is with the isotron. If it's actually
exciting its mast (as some antennas do), then maybe I could use a similar
technique to excite the balcony rail itself.

A loop is not out of the question either, but to be at all efficient, it
would have to be made of 1" or even 2" copper pipe.

If you might consider a loop antenna, check out two electronic books, which
are produced by antenneX Online Magazine. The two books are "The Loop Book"
by Ted Hart, W5QJR, and "Small Magnetic Loops, Construction & Use" from
antenneX. See
