Steve,
You might want to consider another possible solution....
I don't know how much wire is involved - but the entire length of EHS
did not stretch - I would cut off maybe 15' or so on either side of the
stretched area, connect the cut-off ends to an insulator with preforms
on each side, and then add another piece of EHS with insulator and
preforms as necessary to make up the required overall Guy length.

I would replace the wire. EHS is not stretchable, so no doubt it was
damaged.

I should have mentioned that the guy wire in question is ~330' long,
and elongated by ~6". I know - it's amazing that it didn't break.
It's a fair ways from yield (fy) to failure (fu) for steel. I don't
know the alloy here, but looking over a table, it looks like fu is 10%
higher than fy for most of the "high strength" steels.
EHS 3/8" seems to be 15,400 lb breaking strength.

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?
TIA
