Don't know where you are from, or what your local cable company policy is, but they get real upset around here when people mess with their installations. Unless you work for them, and authorized, you can't even run your own cable to other rooms in your house. You pay for the service, not the equipment. 100 meters would provide the neighborhood with free cable TV, definately jail time for the provider... Why not just get satelite TV, pretty much the same stuff on both.
