How accurate are the results for 2 meters for YT?  Anybody know?
I've gotten some puzzling answers from YT.  I don't have a tower  at my home 
QTH and have had my 2m yagi at 10' to 12' above ground. YT says good ground 
gain at that height but I'm not sure how much to believe it. Results have been 
much better than expected,  but I suspect putting it up to 50' or 60' would be 
better still.  Being on a hill helps a lot.

How far above ground should a yagi be to avoid any loss to ground interactions? 
(for a Cushcraft 17B2, about 30' long).
