You might want to look at an article in QST by K6STI, who experimented/made a "noise-cancelling" antenna. It was a wire antenna, 25 or more feet on a side, with open wire feed lines from two opposing corners that went to a center pole and box with a matching xfmr, etc. One of the feed lines was twisted 180 deg to cancel local noise signals. QST article was Sep 1995, page 33. and pages following....might be worth a look. I built one of those a few years ago, and still have it. While it occasionally provides better reception than my other antennas, most of the time its performance is disappointing. I pretty much consider mine wasted effort.
