Ken & Pete,
Thanks for sharing the rotator loop info.
I am changing the coax on my tower and have been trying to think of a better
way to do the loop. I like this idea and will try it myself.
Now I need to decide whether to start with the rotator at mid travel or all the
way around. Probably doesn't make much difference,
the yagi is 8 feet above the rotator..................
73,
Bob
