Does telephone wire produces interfrence or bad reception if it is used for Cable TV reception?
I have used telephone wire in place of conventional coaxial cable to receive Cable TV. But the picture as well as sound quality I am getting is not good. Is it due to telephone wire and should I replace it with coaxial cable? Yes you should. This cable does not ‘receive’ the signal, but instead just carries it from the supply cable to the TV. A coaxial cable is shelded, and its impedance is matched to both the supply cable and the TV over all of the frequencies you need. Telephone wire isn’t even close to that.
