The torque spec on the T2X is 3400 ft lbs (weight x turning radius). The turning radius of the EF240X is 25.1' the weight of the two antennas; /archives//html/Towertalk/1999-09/msg00020.html (8,473 bytes)

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.
