    First, the K-Factor (and Hy-Gain's Effective Moment) are both ESTIMATES 
of rotator capacity.

    You lost me. The turning radius is a distance measurement so at what 
point on the turning radius would the weight be? 

    The K-Factor (weight times turning radius) is a more realistic way to 
rate a rotator than the old antenna square footage method since it takes the 
footprint of an antenna into account; it could take more rotator torque to 
turn a small, heavy antenna than one that is big and light.
