I had the KJ7U screwdriver vertical mounted in the attic, with 25 radials
splayed out across the floor. It loaded up on all bands 160 to 2 with very low
SWR. It worked OK, but the current fan dipole set works better on 40 and above.

John,
If I'm not mistaken, the Tarheel is using your mobile home as a ground
plane. If you put it in your attic, you will have to make an equivalent
ground plane for it to function properly. If you do that, and your roof and
attic walls do not contain enough metal to shield RF, what you suggest might
work.

Frank,
I have a Tarheel antenna that I use on my motor home. I have been toying
with the idea of put a mount in the attic and putting the antenna on it
when
the motor home is in storage. I use the capacity hat when mobile so the
antenna is not much higher than the air conditioning unit when mounted on
the top of the ladder.

John

My 40 meter dipole seems to work quite well, and 20 is OK. During the SSB
and CW sweepstakes, I had nearly 100% response to calls on 40 and 20. They
won't load up on 80 or 160, however. And no amount of thought will remove
the large amount of metal in the attic, including the cable TV coax, power
lines, air ducts, and furnace. There isn't a spot in the entire attic that
isn't a few feet away from something metal. I'm sure some of the power is
going into that sink.
In addition, there are trusses on 24" centers throughout the attic, which
makes moving around very difficult, especially in view of the fact that I
am
disabled. An outdoor antenna would be easier to erect, and probably work
better.

I am running a 40 meter dipole and a Mosley Mini 33 tri bander in the
attic,
beam is fixed pointed to the northeast, and have DXCC using QRP.
They work well when given some thought.
