mast cancels any torque??


        I'd love to but it took  Dick Weber, K5IU, (a Professional Engineer) 2
3 pages of lots of calcs, graphs  and illustrations to show it. It's in 
Communications Quarterly from 94 and  95.
 
        And it's wind torque. The  torque of one antenna on one side of the 
mast cancels the torque of the antenna  mounted on the other side of the mast. 
Two identical antennas mounted on  opposite sides of a mast will result in 
zero mast torque.
