G+_Rud Dog Posted July 13, 2018 Share Posted July 13, 2018 Comcast offers Cable TV and Internet service. Both signals are carried by one cable. If I decided to discontinue Cable TV service and kept Internet service could the Internet service and OTA antenna signal coexist on the same cable? This would allow the connection of an OTA antenna at the entry point of the home. Also, would my signal from my OTA antenna back feed onto the cable outward bound?

G+_Black Merc Posted July 13, 2018 Share Posted July 13, 2018 Best to keep the two separate to keep the cable co. from getting pissed... To easy to send cable back out over antenna... Co. has trucks with detection equipment of cable signals to detect "stolen" cable. Link to comment Share on other sites More sharing options...
G+_Walter Allen Posted July 13, 2018 Share Posted July 13, 2018 They will not coexist on same cable Link to comment Share on other sites More sharing options...
G+_Jared Twomey Posted July 13, 2018 Share Posted July 13, 2018 It all depends on what channels you receive (which frequencies), and what frequencies your cable company uses for their modems. It they are not overlapping, you could use a diplexer or combiner to do what you propose. The problem is the frequency range both of those use are the same range, so it is probable they would interfere with each other. As others mentioned, not a very viable solution.

G+_Eric Hudish Posted July 13, 2018 Share Posted July 13, 2018 Last time I checked you could still access local channels from the comcast line anyways. I believe there's some FCC requirement about required open broadcast for local channels - though don't quote me on that. In any event, easy enough to plug coax directly into a tv and try it out, would be less frustrating than trying to deal with an antenna constantly.

G+_John Gilbert Posted July 13, 2018 Share Posted July 13, 2018 No, because you'd have to unhook the cable from the modem in order to run it from the antenna to the TV. It's best to run a separate cable. Link to comment Share on other sites More sharing options...
G+_Mike Lambert Posted July 13, 2018 Share Posted July 13, 2018 I was able to successfully do what you are trying to do, but the folks above are correct. You can't run them on the same cable. All of my CATV lines went down to a central location in my basement to an amplifier. I disconnected the feed from the cable company (Cox in my case) from the amplifier and connected that line straight to the Modem. Then I put up an indoor OTA antenna near the primary TV and connected it to the feed end of a splitter. One output from the splitter went to that TV and the other connected to the line that went into the wall and back down to the basement. This line then became the feed for the amp and provided the OTA signal to the rest of the outlets through the house. Link to comment Share on other sites More sharing options...
G+_Rud Dog Posted July 13, 2018 Author Share Posted July 13, 2018 Eric Hudish I was using this exact method to watch local channels years ago but Comcast has since somehow stopped that from being true. Link to comment Share on other sites More sharing options...

G+_John Sullivan Posted July 13, 2018 Share Posted July 13, 2018 Mike Lambert but he wants to keep his Comcast cable connected (for Internet) not disconnect it like you did. Link to comment Share on other sites More sharing options...
G+_Black Merc Posted July 13, 2018 Share Posted July 13, 2018 John Sullivan Mike Lambert did! "Cable to cable modem". Ota to amplifier and tvs. Link to comment Share on other sites More sharing options...
