Yes I have. I'll take a look at my notebook and get back to you. There must 
be 10 oaks surrounding my old antanna site. When the temp dropped down to 
zero the antenna current used to go up by as much as 2.5X and was the only 
time the antenna performed well. (This was for totally frozen ground before 
and after). The reason was assumed to be the sap in the limbs heading 
underground.

What did you compute as the total system AC resistance for your antenna? 
(coil + ground + other)

Later,
