I used to live on a hilltop that was line of sight to a 1080-kHz BC station a
few miles away. I had a large tiltable-rotatable unshielded tunable wire loop
that could null it >30 dB. _BUT_ this was a groundwave signal of non-varying
polarization. I suspect it's a small loop's ability to null by polarization
that accounts for its better s/n performance, and not the 'shield.'
