rotating tower

[alexevon@abraxis.com (Alex Evonosky)]

        I am getting ready to install a 150' rohn 45g tower.  I was
wondering what would be a good rotator to rotate the tower with a 80m
beam(60' boom) , 20m beam (44' boom), 10/15 meter beam (all force 12's)...
The windload on this tower will be in the range of about 40-50sq feet.  Is
there a rotator that can turn this tower?  Thought rotating the tower would
be better than individual ring rotators.  Thank You in advance,
