Excellent point! Something I do out of habit but failed to describe.

Please be sure to use redundant means of supporting the mast and
antennas. There was an frightening accident a number of years ago when
the bolts on a thrust bearing holding a mast snapped and it fell back
down, trapping the climber by the hands. Don't let this happen to you!
For example, use an extra muffler clamp or two on the mast at the
tower top to secure it.

You should be able to secure the mast and tie back to the tower in 3
places holding it in place. You must have the tower cranked up
enough to access the rotor. pull the plate holding the mast, remove
rotor and rotor plate if needed. Reverse to put in. Alternatively
rent a crane or a man life. You can also crank up the mast if you
have the rotor out with a bottle jack or clamp a come along end to
the mast and tie the other end above and crank away.
All much easier on a Rohn tower with bearing.
