The HDHomeRun Flex 4K is a network-connected TV tuner that is NextGen TV certified. It has 4 tuners: all 4 support ATSC 1.0, and 2 of them also support ATSC 3.0. ATSC 3.0 provides 4K video. An external antenna is required.
It sends live TV to multiple devices at once, so several people can watch in different rooms. Connect a USB hard drive to get a whole-home DVR with no subscription. A paid TV guide is available for advanced auto-record features.
It cannot tune DRM-protected channels. ATSC 3.0 content is supported only when it is DRM-free.
