Thanks for all the responses...
To answer all the questions...
Inverted V was up when I made the initial measurements
Yagi was pointed at EU for both checks...I'm in the Northeast. Turning the
antenna 360 degreees makes no difference.
The day before I checked it we had about 2 inches of rain. Prior to that I
believe the ground was pretty much frozen. There is probably still a lot of
moisture in the trees surrounding the tower.
And tomorrow is predicted to be a sunny day and mid-40s so I'll get out and
drop the 160 low dipole.
Thanks to all...
Doug - K1ZO
