Yep, that's why I bought that property.
Just wanted to say that what I always do is listen to many
signals and A/B two antennas against each other. Thus, whichever
one wins has better gain at whatever angle the signals are
actually coming in at. Basically, I don't care what that
angle is, I just want the antenna that works best with the
signals I want to receive. The trouble with measuring gain vs
elevation angle, even if you own a helicopter :-) is that you
still need to know the angle the signals are coming in at.
How do you measure that?
Even if you knew my elevation pattern, "your milage may vary"
as the saying goes. Different ground condx, different propagation,
etc.
