There could be a better way, but I have always used a come-a-long
attached to the top rung of the tower and a muffler clamp around the
mast, wrapping the cable with the hook around the mast below the
clamp, Loosen the bearings so it will slide through and have a short
2x 8 board handy to rest the mast on to reposition the clamp to go
higher.
I suppose a gin pole, fully extended, with a clamp on the mast
already through the top of the tower would also work and could be done
with everyone on the ground until after it is extended to where you
want it.
