I can't remember where I heard it, but something sticks in my mind about using "terminators" on cable tv lines that don't end up at a device (a tv or recorder,etc). I have split the main cable line that comes into the house and have run a couple lines to rooms that I might want to put a TV some day, but for now these lines aren't connected to anything. Should I be using "terminators" on them? I don't have a clue about what I'm talking about on this subject or whether it is even correct. Can someone educate me on this?
