I'd avoid it. The conductivity of steel (stainless?) guy wire is much
lower than copper, maybe 40 times lower, so your 3/16th EHS is maybe
something like 20 gauge copper equivalent.

I don't recall seeing it anywhere, but is there any problem with using some
left over guy wire (3/16 EHS) to go from the tower to a ground rod at the
base of a tower. Planning on going to about 60 feet with Rohn 25 and will
probably use a ground rod at the tower and maybe one at each of the guy
points. Just seems to me that if the correct clamps are used the wires and
tower would be the same material and not have a galvonic reaction.
