Our take on the SiliconDust HDHomeRun Flex 4K

The HDHomeRun Flex 4K is a network TV tuner that puts free over-the-air channels on every device in your home over Wi-Fi or Ethernet. It has four tuners: two handle the newer ATSC 3.0 (NextGen TV) broadcasts and all four handle standard ATSC 1.0. It records to a USB hard drive you supply, with no subscription needed for basic DVR. It suits cord-cutters with a good antenna who want broadcast TV on phones, tablets and streaming boxes. Against single-tuner boxes it is far more flexible, but ATSC 3.0 playback is limited to DRM-free channels and to newer hardware such as the Roku Ultra 4800X.

Up to four ATSC 1.0 streams at once, or two ATSC 3.0 streams, depending on what is broadcast in your area.
