My point exactly. Here my antennas must be elevated to at least 25 - 
35 degrees to get a shot at the sky (in most directions) just to see 
the sky. With S Band I probably need 40 degrees or more. So tests 
done at low elevation are of no concern to me. I wish I had horizon 
to horizon view of the sky for satellites but the trees keep the 
house and buildings much cooler here in the summer so i do not 
complain. I work sats in the winter when the leaves are gone.

As more and more phones and computer networks go digital and move to 
5.8 ghz I think that will actually clear the 2.4 ghz band for us. 
Just a layman's opinion.
