Is Comet free with an antenna?
Yes. Comet is broadcast free over the air on a subchannel of a local station, so a TV antenna picks it up with no subscription. Run a channel scan and it appears with the station's other channels.
Why can't I find Comet after a channel scan?
First check that your city is listed on this page and that the station's signal is rated Strong or Moderate. Stations sometimes move networks between subchannels, so rescan your TV if the channel goes missing. The channels here are from data as of November 6, 2026.
Do I need a special antenna for Comet?
No. Every station listed here carries Comet on a UHF channel, which almost any TV antenna receives.
