Bill,

When you climb up, take along some rope, a pulley, and some clamps also.
Unless you have two strong tower workers, you may find the antenna to be
too unbalanced to pull through the boom to mast plate without some additional
support.  Mount the pulley on the mast high above the antenna and run the
rope far out the antenna boom like a truss.  Use this truss arrangement to
keep the boom from dropping and catching on the guys, etc.
Initially, as Steve would say there is a pucker factor, but it will go easier
than you first believe.
