Well, you can ignore most of what I scribbled. Welcome to horizontal
polarization. My guess(tm) is that a horizontal yagi or dipole in the
attic is going to have problems due to all the wiring and possibly
conduit in the attic. A vertical is at least mostly away from the
wiring, but a horizontal antenna lands right in the middle of the
mess. There's also the not so wonderful noise produced by electronic
ballasts, LED lighting inverters, and ceiling fans. I guess(tm) that
an outside cross polarized vertical or loop antenna would work better
than anything horizontal inside the attic.

A rotary array would be difficult in the attic, but switched directive
arrays may be possible.

Or, a non-rotating electrical wire horizontal yagi between the
rafters. There are also temporary antennas that can be rolled out
when needed, and hidden when the neighbors arrive in force:

Because all of the CW/SSB action is at the very bottom of the band, a
narrow bandwidth antenna works just fine.

Time to spend some effort with EZNEC.

I suggest 4NEC2 instead:

The program includes a substantial number of common antenna models to
plagiarize.

Dual 5/8 wave 50 Mhz vertical (without matching xformer):

Thanks, I'll give it a try.

By the way, I have no homeowner's association constraints. It is a normal
sized house on a small lot that slopes down in the back, and has no suitable
trees.
