I have three sets of two attached to my 70' ham radio antenna tower. I'm VERY careful when I'm anywhere near those guy wires. It's my tower and my money involved.
It's one of the 3 areas that I'm the only one allowed to mow. (Along with the ditch & the area around the woodpiles.) Fortunately, it comes down at just steep enough an angle that I can almost treat it like the pole & just skim around it. Any shallower an angle & I'd reach for the weed-wacker.
Somebody Posted about hitting a guy wire with their rops the other day.
I don't know who the poster was or the name of the thread and couldn't find it after doing several searches,
