Our take on the SiliconDust HDHomeRun Flex Duo 2 x ATSC Tuners - HDFX-2US

The HDHomeRun Flex Duo is a two-tuner network TV device that takes an over-the-air antenna signal and streams it to phones, tablets, computers and streaming boxes over your home network. It works with ATSC broadcast channels and also records to a connected USB drive when you add the DVR service. Its main draw is that two tuners let one person watch live while another records, or two people watch different channels at once. Compared with single-tuner models it is more flexible for households, and compared with the Flex 4K it trades next-gen ATSC 3.0 support for a lower cost and simpler setup.

  • No subscription needed for live TV; guide data and DVR are optional
Cons
  • Needs a decent antenna and signal strength for reliable reception

Questions and answers

Do I need a subscription to watch live TV?
No. Live viewing over your network works without a subscription. The paid service adds guide data and DVR recording.
Can it record shows?

Does it work with Plex?
Yes. Plex, Channels, Jellyfin and the HDHomeRun app can all use it as a network tuner.
What antenna do I need?
Any decent indoor or outdoor ATSC antenna. Reception quality depends on distance to towers and obstructions, not on the box.

The Flex 4K adds ATSC 3.0 tuners for next-gen broadcasts. The Flex Duo is ATSC 1.0 only but simpler and cheaper.
