    For fir trees here in the Pac NW with some minimal growth left, they'll 
last indefinitely. 

    Tree tar doesn't seem to make any difference here but YMMV.

    Not in my experience. Everything below the antenna is ALIVE. People top 
trees all the time around here to reduce tree windload with no problem. 
Remember I said I WASN'T an arborist.

    No. While I have always used tree spurs, the newer way of doing it is 
with ropes thrown over branches and then you use climbing ascenders to go up 
the rope and descenders (like a figure 8) to rappel down.

    Recreational tree climbing is a growing activity in the US. There are 
lots of good websites with information on them.

    What are you, some sort of sado-masochist? Where would you mount it? How 
would you mount it? It weighs a ton and you've got little or no leverage as a 
person in the tree. A simple pipe mount is simple and manageable.

    Go for it!

    A couple more things. Antennas in trees are electrically floating in 
space since there is no metal tower or guy wires in the vicinity and antennas 
in them play like GANGBUSTERS!

    Also nothing on the tree is plumb so you just hope to get the mount 
"pretty close". Also it's high maintenance - around here every 4-5 years you 
need to clear the new sucker branches. A branch smaller than your little 
finger can successfully hang up an HF yagi. 

    And IT'S WOOD.
