The legality of activating outlets would be specific to the cable company right? I use Charter and the TOS do not seem to be on their website and a Google search turned up nothing. I am not particularly concerned about this, I think I mentioned to a cable installer once that I had installed a few outlets. I'd rather not involve the cable company. Last time I called them they had no idea what they were talking about and could not help us with a seemingly simple billing issue. So I guess the first thing to do is properly crimp all the cables. Also, I had never heard of RG8, only RG6, is it worth running RG8?
