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.
Roku compatibility:
The Roku Streaming Stick Plus (released 2025) is not (yet) compatible with broadcast television and will not work at this time.
The following Roku models support ATSC 3.0 channels: Roku Ultra 4850 (released 2024), a Roku Ultra 4802 (released 2021), Roku Ultra 4800 (released 2020). Older Roku models, non-Ultra models, and LT models do not support playing ATSC 3.0 channels.
Certain Roku audio settings can result in no audio being heard. This is easily fixed. The HDHomeRun app will detect the problem and display instructions explaining what setting to change to fix the problem.
Watch Live TV from different devices
Depending on which HDHomeRun product you choose, you can be watching Live TV wherever you want in your home, whilst another family member watches a different channel. On a different device. In another room. Add more HDHomeRun products and more people can all watch live TV simultaneously.
HDHomeRun. Endlessly expandable.
Internet connection is required to use the HDHomeRun apps with the HDHomeRun FLEX 4K.
ATSC 3.0 DRM: Some ATSC 3.0 channels may be DRM encrypted and will not work. If an ATSC 3.0 channel is DRM encrypted the HDHomeRun FLEX 4K will use the ATSC 1.0 version of the channel. 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.
