IMPORTANT: Please check the RabbitEars website to see if the ATSC 3.0 channels in your area show a padlock icon indicating that they are DRM encrypted. ATSC 3.0 channels that are DRM encrypted will not work. DRM encryption is used by select broadcasters to block out-of-home viewing, limit what player devices can be used to watch TV, enforce that the original tuner hardware is always present to view recordings, and to block third party apps. Optionally a broadcaster can force recordings to expire after a period of time and/or block recording completely. If all ATSC 3.0 channels in your area are DRM encrypted you can use any HDHomeRun FLEX model to receive channels using ATSC 1.0.
