      Sort of. If you're going to include the mast, you need the turning 
radius for it too. For practical purposes, just calculate the Effective 
Moment for the antennas and forget the mast. 

      This will give you:
EF-240:  24.2 x 32 = 774.4 ft-lbs
C-31XR: 23.8 x 82 = 1951.6 ft-lbs
Total:  2726 ft-lbs. 

      The T2X has a capacity of 3400 ft-lbs so it can turn the array.
