So I'm going to undertake a project soon to install a Cable TV jack at the stern. This is primarily for hooking up cable while at the dock (free with the marina) and possibly also cable internet.

My one question here is how I ground the new jack -- I *think* it needs to be grounded as I'm introducing a new source of current leak to the boat. Do I connect the ground (outer jacket) it to my galvanic isolator? Do I introduce a ground loop isolator into the coax line? What's the right thing to do here? How have others done it?

Thanks!

ps: will post pictures and updates from this project as it is underway...
