<< Roger...
Several years ago I had the same problem with a bent mast and TH7 with a
2
meter antenna above it. Also keep in mind I had a "schedule 80" mast pipe
in
place. After several of us had headscratched for a while, we decided to do
the following....it worked great for me, and may be a solution for you.
1) Tie a strong rope as far up and "above" the bent place as
possible.....
2) Tie another rope to the area of the "bend"....just "below" the bend
and just above the bend. This is a simple "bridge" of the bent place on
the
mast.
3) take a hacksaw, and SLOWLY saw and gradually weaken the "bent"
part....while simultaneously letting the ground crew pull downward on rope #
1.....as the cut weakens the mast, and tension pulls downward....the mast
will bend downward, and the antennas will be reachable as the mast folds
over. You can gain access to the antennas, and remove them this way.
4) Rope #2 is a "safety" measure that spans the bent area that you are
sawing through, in case the mast totally fails as it is being sawed and
weakened. In my case, the mast collapsed and folded over gently, but rope #
2
is a MUST in case Murphy is around.
I hope this suggestion helps you or someone else......I am sure there are
other ideas and better ones, but this worked great for me, and I would not
hesitate to do it again.

P.S.S. Sorry Roger...there was another step in there....Have your gin pole
up there, and tied at the same place that rope # 1 is, above the bend as high
as possible.......the ginpole will be your safety measure and shock absorber
"if" the pipe starts failing and tearing faster than you planned
for......hope this makes sense. Rope # 2 keeps any movement to a minimum
"if" the pipes breaks also. Its fairly straight forward, and you can simulate
some of the operation from the ground before going up.
