I noticed a bit of a rubbing mark on the antenna cable today. From my guessing, it has been rubbing against the frame of the Inspire. I hear the cable is a coax cable. For it to be damaged, the cable has to be cut completely off? I've been seeing people putting things around the cables so it protects it. Is this necessary at all? I assume the rubbing mark that is seen on the cable now is because when the arms go up. Hopefully this rubbing mark doesn't lead to any damage to the outside layer of the cable in the future. Should I be concerned at all or will the cable be fine even with some rubbing mark on it? Thanks in advance.
