Okay. I guess my thinking was along the lines of my situation. I too have a
horizontal extension on the tower to support my inverted-vee. But my load is
entirely vertical with the apex of the antenna directly under the pulley.

GM Wes and happy thanksgiving !
Surprisingly when the rope (knot portion with antenna) is hoisted up and the
antenna pulled tight that still tightens up those vertical ropes. Do you
remember that problem we were all given in college to calculate the tension in
a rope if you pulled on it in the middle perpendicular to that rope? Even
though that perpendicular pull is WAY WAY off on one end it still seems to
pull it out and away from the tower almost a foot stretching the entire
vertical ropes.
Probably did a poor job explaining that but in the end the tension in those
vertical ropes does increase when the "dipole" is made nice and tight and 30
or so pounds of tension is applied. Add to that some wind or 1/2" of ice and
that 30 pounds seems to turn into several hundred pounds of tangential pull.
