Are you saying that you glueing lengths of this tape together to get your counter poise?? If so, doubt it will work unless you electrically connect each piece. If it's long lengths of the copper stuck onto the hull
or whatever, with the adhesive
backing, don't think it would be a problem. I used 3' wide copper copper strapping, under the deck
, down each side of my boat for a ground plane and it works fine. Didn't splice it just ran about 35' of the strapping from the tuner in the lazerette to the bow. It's not grounded to anything except the tuner.
