"Try listening to K3LR running EU on 80M and think again. Ohio/Penn soil is
not salt water and a 4 sq is a 4 sq. So if the extensive ground screen over
elevated radials is so useless - what is your explanation of the
performance."

a 4-square is not a 4-square.... I have had several iterations of 80m and 40m 
4-squares here.  starting with 48' base loaded pipes with radials on average 
ground, to the same 48' ones in a swampy area with added radials, to full size 
wires hung around a tower with a single radial and then with extra radials and 
on-ground screen, and now finally to rohn 25 towers with raised radials at 10' 
at first with additional on the ground screen and now without... the extra 
ground screen was a waste on the tower 4-square, I just did it because I had it 
left over from the wire one where I think it helped a bit.  The tower 4-square 
way outperforms all the other iterations.
