I am researching and hopefully moving from a couple of tivo's to an HDTV set up and a nice plasma. I have my lines going to a terk multiswitch with 5 lines out, 2 tivo's and a single to another tv. To grab the local HDTV broadcasts with an antenna in the roof, can the coax for the antenna be ran into the UHF in on the terk and than spliced out from a tivo line at the tv? Or do I need to run another line <sigh> through the walls just for the OTA antenna? Thanks!
