[TowerTalk] trees and verticals

Where did I say they won't work?  I said exactly the opposite.  They 
"work" even if they may be lossy simply because 1 or 2 S-units (or 
whatever the penalty may be) is still not that severe when compared to 
the relatively low power to a good antenna required to make a contact.  
I said they don't work as well as the same antenna in the clear and I 
think that is rather irrefutable unless you (or AC0C) has some 
comparison data to the contrary.  Do you?
