The HDHomeRun FLEX 4K is a network TV tuner that receives free over-the-air broadcasts from an antenna and sends them to devices around the home over Wi-Fi or wired Ethernet. It has four tuners: two support ATSC 3.0 (NextGen TV) where available, and all four support ATSC 1.0. Up to four devices can watch live HDTV or 4K at the same time, at resolutions up to 3840x2160.
Connecting a USB hard drive adds whole-home DVR for watching and recording. No subscription is required for DVR; a paid TV guide is available for advanced auto-record features. The tuner needs no cable TV subscription or cable box.
ATSC 1.0 content works with Android, Fire TV, Apple TV, Roku, Sony, Xbox, iPhone, iPad, Windows 10/11 and Mac. ATSC 3.0 DRM-free content works with Android, Fire TV, Apple TV, Roku Ultra 4800X and newer, iPhone, iPad, Windows 10/11 and Mac. DRM-protected channels are not compatible.
