The 10 dB assumed that it was replacing an antenna that wasn't high enough
to perform well, so some of that gain comes from the tri-bander pattern,
and some from the 70 ft height.  But that requires one of those pesky tower 
thingies. :-)

Jim, I'm impressed with your redwoods!  I did some ziplining in a north-central
California redwood forest a few years ago, and it was amazing.

There's no such thing as a tree-supported antenna at 120 ft here in Vermont.
I consider myself lucky to have an inverted vee with an apex at about 50 ft, 
near
the top of a large tree by the house.

73,
