Jim not sure if this was what you were after but in one of your paragraphs you
said " What I’ve not looked for recently is whether anyone has modeled whether
the direction of the wire or whether just dumping chopped up wire into the soil
works. " this reminded me of something from many decades ago.
When I got out of school my 1st job was with a firm in Northern Virginia call
Atlantic Research Corp. It was really an awesome place to work and they had a
terrific technical library. Anyway, after several decades of hostile take overs
etc the company was swallowed and had to dissolve. They told the employees to
help themselves to any books in that library. I was late to the party but I did
snag a couple dozen gems.
One was a study that was done by, I think, the USN down in Antarctica. They
wanted to see the effects radials had on the directivity of different vertical
antennas on different frequencies. Someplace down in the dungeon I should still
have that study. Anyway, in some cases they ran stupid long radials but in very
limited directions (like a gob of them over just 5 degrees then 10 degrees etc
etc) then they measured the verticals azimuth directivity by way of FS. I seem
to remember the radials were many, many miles long in some cases laid on the
snow surface. Bottom line was that very directive and efficient antennas could
be had if you had enough real estate. 73 Gedas W8BYA
