I would not worry about trees and Yagi antennas. Until real recently I had a
40 foot tower with 3 cushcraft beams 20/15/10. The 20 meter beam's reflector
actually hit tree branches at some directions. I worked and confirmed 336
countries in 11 years with these antennas between several 90 to 120 foot
trees. I am sure some experts on the reflector will disagree with me, but I
got the cards to prove it. Look it up W3OZ. Larry
