My house is wired for tv (coax) and I have canceled my Fios cable tv and digital voice, so I now have Fios Internet-only service. Can I connect a local antenna (w/amplifier if needed) to the coax to distribute a tv signal to my outlets without interfering with the Fios internet signal that goes to my modem/router? I don't know how the Fios signal gets to my router, and whether putting a signal on the coax network would affect that.
