    Ouch! This will be a rotator and tower killer. The Effective Moment of an
antenna on those parts is the product of the weight and turning radius. A
MUCH heavier antenna will play havoc with the tower integrity. A 3L 40M
antenna will be 2-300 pounds anyway. It's a major antenna and rigging
challenge and not for the faint hearted.
