Hi Thom,
The loop can be a antenna of choice for QRN/ QRM areas. The end fed antenna
being unbalanced may have more noise than the loop. You will end up with
more of a rectangular loop, or a horizontal "Hentenna".
For the higher bands, 20 and up you might investigate the compact beam
designs like the Moxon rectangle.
You might have to consider a loaded dipole. Even a loaded dipole, although
shorter, will also carry the advantage of being a balanced antenna with
fewer feeding unknowns.
I would avoid running over neighbor's roofs, etc. and keep your antenna on
your own property.
Now you might try vertical dipoles. Sleeving the feed by bringing it down
inside the tubing has shown on the Gap Titan, that the result is less noise
pickup than with conventional quarter wave dipoles. A vertical of the "half
wave" type, with linear decouplers for various bands can be a very good DX
antenna when the bands are open.
