I'm exploring adding OTA, with the possibility of dropping cable altogether. What I'd like to do is use the existing coax that's run in my apartment to carry the signal from an attic antenna. Is it possible to have both OTA and Cable on the same wire? At the wall by the Tivo, I'd have a splitter with one "branch" going to Antenna In, and another going to Cable In. I'd like to try both OTA & cable for awhile to make sure I don't prematurely cancel cable only to find out I can only receive 1 channel OTA! Would this work? I'm already sharing the coax with my network using MoCA adapters.
