Lets not lose focus though - this is about the on ground loop. For SWL / ham-swl's, this can provide some unique opportunities for antenna placement with a little imagination. Needing no supports is obvious. Pretty stealthy. No hoa concerns. Just keep it safe so nobody trips over wires. For apartment / condo dwellers, where there may be no access or restrictions to the roof, or performance with a small vertical loop inside the residence is not performing well, the mere fact that this is outside and possibly away from a structure is a big advantage. Thoughts: if you have a small yard area, or even a common little patio shared with others, it might be possible to run a loop around the perimeter and not raise any eyebrows. On the second floor? If you can run a small coax DOWN to this little lawn area - bingo. Can't run coax? I've even used zip-cord in a pinch as the transmission line to the 9:1 since it isn't so critical overall. Here, I'd definitely recommend a common-mode choke on a coax transition. Don't choke the zip-cord, put that on a transition. If you use your imagination, the on-ground loop can provide some other options to getting your antenna *outside*, even if that means on the ground, which may perform better than anything inside.
