If it were me, I would just use coax fed dipoles. OCF may have some feedline
radiation issues. AC0C has a lot of experience with attic antennas and it
would not hurt to look at his site.

Greetings!
I will be installing an AH-4, paired with an ICOM 9100, in the attic of
a 4-story condo. My original plan was to set up either a 20M or 40M
dipole, one off of each leg (center and gnd) of the AH-4. Then I
thought, why not experiment with an OCF configuration? Either way, I'm
60' from the earth so grounding the AH-4 would be difficult, if not
impossible.
My question is, what experience do you have using an auto tuner/coupler
and different antenna configurations (dipole, OCF, long wire, etc). Any
recommendations? Getting into the attic for multiple tests will be
difficult so I'm looking for a solid starting point!
