            I really do get what you are saying, Howard, which is why I'm 
wondering if something was going on up there on top of the manager's RV that 
I did not know about initially.

It just seems strange that the antenna looks fine on the ground, at least 
upon initial inspection.

Believe me, I'm going to check all antenna and feed line connections 
thoroughly before putting it up again, and this time, we'll do it in trees, 
as I originally had planned.

Once again (and I know I have said this before), I appreciate everyone's 
patience with this entire problem-solving exercise.
