Our take on the SiliconDust HDHomeRun FLEX DUO

The HDHomeRun FLEX DUO is a two-tuner network TV box that puts free over-the-air ATSC channels and unencrypted cable channels onto your home network. Any phone, tablet, streaming stick or smart TV running the HDHomeRun app can then watch live TV, and plugging a USB hard drive into the box turns it into a DVR. It suits cord-cutters with an antenna who want live broadcast TV in several rooms without renting extra boxes. Against the four-tuner HDHomeRun CONNECT and FLEX 4K models it trades tuner count and ATSC 3.0 support for a lower entry point, and it needs a separate antenna and a wired or Wi-Fi network to work.

Pros
  • Two tuners let two people watch or record different channels at once
  • Works with Android, Apple TV, Fire TV and Roku through the HDHomeRun app
  • Records to a USB hard drive you supply, with no subscription required
  • Small, fanless box that sits quietly near the router
  • Ethernet port plus Wi-Fi gives flexible placement
Cons
  • No ATSC 3.0 tuner, so next-gen broadcasts are not supported
  • 1080 maximum resolution, no 4K
  • No remote and no on-screen guide without a separate app or service
  • Needs a good antenna and a stable home network to be reliable
  • Only two tuners, so a busy household can run out of streams

What reviewers say

Owners of the FLEX DUO generally like it as a simple, low-maintenance way to get antenna TV onto every screen in the house, and the built-in DVR with a USB drive is a common selling point. Complaints center on the two-tuner limit, the lack of ATSC 3.0, and the dependence on a strong antenna signal and a solid network.

Questions and answers

Do I need an antenna to use it?
Yes. It has no antenna of its own, so you connect an indoor or outdoor antenna to pull in over-the-air channels. Unencrypted cable can also feed it if you have a cable line.
Can it record shows?
Yes. Plug a USB hard drive into the port on the box and the HDHomeRun app can schedule and store recordings. There is no built-in storage and no subscription needed for recording.
How many people can watch at once?
Two. Each tuner handles one live channel or one recording, so a third simultaneous stream has to wait or share a channel already tuned.
Does it support 4K or ATSC 3.0?
No. It is an ATSC 1.0 tuner with a 1080 maximum resolution, so it will not receive ATSC 3.0 broadcasts or output 4K.
What is in the box?
The FLEX DUO unit, an AC power adapter and a quick-start guide. You supply the antenna, the Ethernet or Wi-Fi connection and any USB drive for recording.
How is it different from the HDHomeRun CONNECT?
Both are network tuners, but the CONNECT line offers four tuners and some models add ATSC 3.0. The FLEX DUO is the smaller two-tuner option for lighter households.
Where is the SiliconDust HDHomeRun FLEX DUO cheapest?
At Walmart, for $109.99, as of our latest check.
Where can I buy the SiliconDust HDHomeRun FLEX DUO?
5 stores we checked sell it, including Walmart, Newegg.com, eBay, Scierie Touchard Bois, Amazon.
