The problem we have is that two of the three guy anchor points are under an adjacent structure roof overhang and will not allow us to guy the tower at or near the top. One of our club members has proposed a novel idea for deviating the guys around the roof overhang - please see the diagram below. Has anyone ever tried something like this before? Does this look like a good idea or not?
