Have seen several different configurations.
Thoughts on what any might have ideas on.....

If you have a communication receiver and a lot of room running about 400' of wire on the ground(it could also be elevated) makes a great BCB antenna. It's just long enough to receive signals off both the sides of the antenna and off of the ends, too!
I have done this in the past at a little used park near me with my Palstar R30 and it works great.

Must take FOREVER to wrap that much wire - and God help you if it kinks....Mike
I totally forgot one class of gear that might have value - phasing units (notice I didn't say phasers - I don't want the ghosts of Gene and Majel Roddenberry bothering me, heh). I'm not all that familiar with them, but the theory is that you are able to take a signal from 2 antennas and place it either in phase or out of phase, thus either enhancing or nulling it out. Reportedly you can get even deeper nulls than you can with a loop.
I have a few models, with reviews where known, in the article I gave earlier. From what little I gather, the MFJ units need some surgery before they will work on MW, but once done, the results are reportedly impressive.

And here is a post from a long time ago with a picture of the wire spool. This was before I made the linkage. You have to scroll down to post #88.Not too bad. I bought one of them empty reel spools at Home Depot. It's like the ones that hold 100' extension cord and it has a hand crank on the side of it.
Later on I made a small linkage that fits in my battery drill motor and the other end fits into the side of the spool. Now I just use the drill motor to reel the (#22)wire in without any kinks!

I'm quite surprised by this, but Universal Radio is selling several NRC publications on the topic of antennas. Go to the very bottom of this page to see the selection

For AM, depending on how much antenna boost you need, you might some of these designs will be sufficient:
