I pulled this from my boat, I think it's shakespeare. I don't know for sure it is pretty old, but boat is a 2005 so it cant be older than that. It was mounted on those classic ratchet mounts. It worked fine before i pulled it, I replaced it with an AIS antenna. I had to cut the cable sorry there is only 6 inches or so. Asking $25. I'm located near Clairemont mesa.
