Want to mix Off-Air and Cable channels on the same RF Feed?


Unless the site was lucky and happens to have LG sets of the right vintage, the solutions would be:

  • For a distributed antenna system, mix in analog channels. You can use an analog cable modulator between channels 2-14, also Channel Plus makes an analog modulator that support air channels between UHF channels 14-64.
  • If you have a cable system with a limited number of channels*, digital or analog, you can add a few more analog or digital modulators connected to HDTV tuners. That way, you’re converting ATSC to QAM for distribution as an in-house cable system. There are also Transcoders available that can convert up to 2 off-air TV channels into one QAM cable channel.

For the AV and CATV designers out there. More info when you click through to Contemporary Research.
