That is a very minimal stretch if it was evenly over the whole EHS cable, I
assume that you checked to see that it did not just pull out of the
termination. Perhaps the EHS stretched from a single spot instead of evenly
across hundreds of feet of cable which could severely weaken it. Is it
possible that the other two guy cables at that level were also compromised?
Did you check it with a transit level after re-attaching and tightening the
damaged cable? I think that you made a good recommendation that they replace
the cable.

I have a question for the materials crew here. I'm writing up a job report.
Our crew went to a site where a huge tree had fallen on the two lower
guys of a 360' tower. We carefully (well as carefully as we could)
slacked off & disconnected one wire at a time, threw it over the tree,
and reconnected it. At that point the site was ready for the tree crew
to come.
It was obvious that one of the wires (3/8" EHS) had stretched a few
inches. There were enough unused threads in the turnbuckle to enable a
good snug wire again.
I'm recommending that the guy wire be replaced, but was wondering how
much strength in roundabout numbers is lost in this scenario?
