[Lowfer] Another Antenna question - Wet Ground Issue

[jrusgrove at comcast.net]

Based on ground loss measurements with both loop and vertical antennas, 
ground conductivity rises here on both 137 and 500 kHz with increased 
moisture. There is an additional rise with frozen ground but I wouldn't say 
it's anywhere near exponential. This is a hilltop location with a relatively 
high water table (lots of farm ponds around) and is former pasture land.
