I live in a high rise apartment complex and cannot get am in
very good. I cannot put anything out the window. With that in
mind, is there an antenna that will help with am reception?

thanx.

Anything inside will only pick up the ambient noise already
there, better to put whatever you get as close to, if not
actually protruding out of, any window you have. Reason is that
any most AMBCB signals indoors consist of stronger QRN than any
desired stations, which can't compete.

Actually, a shielded loop, like a DA-5 is surprisingly resistant
to
locally generated noise.

I've used a DA-5 for years. Not until IBOC did I start having
interference problems.


Is that performance perhaps due to being able to null the
directional source of local noise?



Yes. That and that it's a shielded loop.

In the 70's, I had it sitting in a room surrounded by tube-type
color
TV sets and could separate 710 KEEL from 720 WGN sitting in St Louis.

It's amazingly resistant to man-made local noise.


A shielded loop design is the best antenna type to reduce local noise
source pickup.
