You will need a very strong mast for all of those antennas which will be
quite heavy. I would look at DX Engineerings 3" 4130 masts. In my opinion,
the easiest way is to install system is to attach the rotator, top bearing
and mast while it is on the ground and have a crane lift it. Then climb
the mast to install the various antennas.

I am wondering about how to install the antennas also. I am planning to put
up a ~35 ft boom with 3 elements on 30 and either 3 or 4 elements on 40
(haven¹t made that decision yet) and a large tribander above it also on a 32
ft boom. It would seem to me the best way might be to put the rotator on the
plate and attach the mast with the top section. But then the antenna stack
install appears to be much more difficult because I have to remove the
rotator at the top, figure out a way to lower the mast to install the top
antenna, push the mast back up, and then install the bottom antenna (and I
am sure I probably skipped a whole bunch of steps even more difficult). The
other way might be to mount the antennas to the mast sitting on the ground,
(if I can find a way to stand the mast up) and then have the crane lift the
entire assembly and drop it through the tower top and thrust bearings.
I am hopeful that I am not the first person who has had this problem and I
would welcome experienced comments.
