Forgot to mention a test I ran in the back yard, quite some time ago, but
have it documented in my notebook. This was back when I recall first
subscribing to this reflector to report the findings (how dull it was back
then <G>). I had run an E-probe up and down 10 to 40 ft to accurately
measure the signal strength change. I also tested a 3ft diam loop the same
way. The signal strength on the E-probe was very close to being proportional
to the height but found no change at all in the signal strength of the loop
with height..... BUT the background noise DID go down considerably with
height.
To eliminate the effect of 'tree shielding' on the E-probe I repeated the
experiment in an open field and the results were the same.
