Just to clarify... Are you grounding the guy wires to protect the tower ?
My understanding is that we ground the guy wires before the anchor to
protect the concrete from taking a lightning hit. I used claps to attach
the ehs 1/4 wire to my copper wire, then grounded it just below to a rod for
each anchor point.
