I just noticed this morning a wire laying on my roof of TT. I got on roof and the wire is a thin coaxial wire coming out of a circular type opening on roof. The end that is sticking out has a thin wire at the end like a coaxial wire. The wire that is still in the hole goes back inside the roof and I can't tell what it is attached to. Does anyone know where this wire is coming from and why did it suddenly appear on the roof. Also should there be a covering for the exit hole because right now the open slit is vunerable to rain it would seem. Help
