I'm quoting your entire message because it's exactly right on all counts.

So rather than just toss the counterpoise wire on the ground, it’s a good thing to keep it elevated — run it from where you have it connected (e.g., table top) out to a bush, a branch, to a fiberglass driveway marker stuck in the ground, whatever’s available.  I carry a piece of small para-cord so I can tie the winder that holds my radial wire off to something.  If you’re inside on a second floor, it may not matter much, but at a typical field site with lousy soil conductivity it can.
