    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

    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 
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

    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.
