First of all congrats on the new tracer 2670bhs.
I had the 2013 version of the same unit. Your right getting the tv off will be a real pain in the butt
they way they ran the wires. So we gave up on trying to move ours outside.
You can buy a bracket at most rv dealers or on line. Im not sure but I think I was told the connection is only for the tv antenna. Maybe someone else would know more on here.
Good luck with your tracer
Carl
