I have done it that way. Also used a brass ring that fits the mast with 3
set screws in it. I put in a second rotor shelf or use the shelf where the
rotor will go. Use the brass ring as a stop that I can slide up or down the
mast. This would give me a positive stop for the mast. It's cheaper than a
thrust bearing.
But now I am lazy. I tilt over the tower. This way IO can get to all the
beams. Need to drop off the ends of the elements as it tilts down, but no
big deal

Subject: [Towertalk] Mounting multiple antennas on mast
I'm have not seen much discussion of an topic that worries me. I'm not
certain I am using "best practices".
How do most folks go about mounting multiple antennas on a mast? Here is
my technique. Is there a better procedure?
I erect the tower with a rotor shelf and two thrust bearing shelves with
the mast inserted through the three shelves without the rotor. Then I
mount and tune the top beam on the mast. Then I use a small "come along"
hoist between the top shelf and a U-bolt low on the mast to raise the mast
before clamping the thrust bearings in preparation to mount the second
beam. The two thrust bearings keep the mast from getting away from me
while I mount the rotor.
Is this the way everyone does it?
