IMO a 6" or so lag bolt is plenty, especially when you've got 4-5 of
them holding the pipe mount. A through-bolt might be a little better but I'd
rather not spend the time drilling thru the tree trunk when the improvement is
marginal.

They make a tar-like material for covering tree pruning areas where
there isn't any bark. It dries up over time and loses its capability so you'd
have to re-do it every once in awhile. You have to send an arborist up the
tree
occasionally - every 3-5 years - to prune the new growth anyway so you can do
both at the same time. It's amazing how much trouble one little sucker
branch can be - one smaller than my little finger can stop the whole antenna
from
turning
> Once the tree is topped, how do you get to the top to rig the rotor/beam?
I climb the danged thing. I bought a set of gaffes - tree climbing hooks
- for that reason. I can do the whole installation with 2 trips up the tree
- once to install the pipe mount and rig the tram and the second to install
the antenna and cables.

I have a couple of times and it makes the job a lot easier.

Well, it's mostly a lot dirtier and a lot more work. Not as much as
fun as when you did it as a kid - hi.
