you will need a yaesu sdx 1000 or the likes. I have the ma770 but modified it
so I do not need to rotate the entire tower.

Subject: [TowerTalk] MARB-550
I am thinking about purchasing the MA-550 with the MARB base (i.e.
rotating tower). What I have not been able to figure out is what size
rotator to buy. Do I just use the wind load area for the antennas, or
do I add something for the torque needed to turn the tower itself. It
seems that it must take more force to rotate the whole thing vs. the
antennas and mast alone.
