So would a Wellbrook 330 or 1530 placed in a window frame be better
than the AOR models. To place a unit outside is not a option for me.

I know two people with Wellbrook loops indoors. They work, but look
goofy of course. In a home office or radio room, who cares if it looks
odd. You need to rig up some support. I use a cement patio umbrella
stand that uses ordinary PVC. OSH sells them. I'm not really sure being
near the window helps since you are receiving a sky wave, not a signal
beamed along the horizon.

I agree that antennas out in the open work best, but HF is not a line
of sight reception. Height doesn't make right for HF, at least not for
a loop. [Beams would be a different story.] . Of course, outdoors means
it won't be close to your noise sources.

I had something kind of odd happen today with my Wellbrook. The
strongest BCB station I can receive is on 680. It is so strong that my
7030 kicks in the attenuator. Even with the atennuator, it reads about
S+40. Anyway, today, the 3rd harmonic of the station, 2040, showed up
in the shortwave band. If I hadn't use the same gear before, I would
have blamed the amp (ALA100) or the radio. The harmonic signal was in
the mud, maybe S4, but clear enough to hear the station ID.

Wellbrook makes other models that are specifically for indoor use.
They're smaller than the 330 and the 1530 and semi-rigid. I don't know
if they are capable of the same high level of performance as the 330 or
the 1530, but the 330 / 1530 couldn't meet their full potential anyway
if you can really only use them indoors.
