ZapperBox vs ADTH: which NextGen TV box should you buy?
Prices and features checked October 29, 2026
The short answer
- Just want to keep your channels? Buy neither yet. No shutoff date exists, and $60 boxes are coming.
- Want a DVR, or NextGen TV on more than one TV? ZapperBox.
- Want live NextGen TV on one TV for the least money? ADTH, or its $70 USB tuner if your TV runs Google TV, Android TV or Fire TV.
- TV has no HDMI port? ADTH is the only one of the two that connects.

ZapperBox: the complete one
ZapperBox is the box to beat if you record shows or have more than one TV. It’s the only one licensed as a full home “gateway” for encrypted channels, which means it can record them and send live and recorded TV to $159.95 Zapper Mini boxes on other TVs. The single-tuner M2 ($199.95) watches or records one channel at a time; the dual-tuner M1 does two. A four-tuner model is also available.
The catches: it’s HDMI only, the whole-home features need a guide-data plan (currently $50 a year for every ZapperBox in the home, with a 30-day free trial; live TV and manual recordings work without it), and it still needs the internet once after each restart to play encrypted channels. ZapperBox says fully offline viewing is working and coming in a future update.
ADTH: the cheap one
The ADTH NextGen TV Box Gen 2 does the basics for about half the price: both old and new channels, 4K HDR, and encrypted channels without an internet connection once you’ve watched each one online once. It also has composite and optical outputs, which matters if your TV or sound system is older. A simple DVR arrived in a May 2026 update; it records one show at a time to a USB drive.
The catches: it’s often out of stock, and reviewers report slow channel changes and occasional freezes. If your TV already runs Google TV, Android TV or Fire TV, ADTH’s USB tuner (about $70) plugs into it and runs as an app instead. It doesn’t work on LG, Samsung, Roku or Vizio TVs, and ADTH’s free Tester app checks your device first.
Or wait for the $60 boxes
Pearl TV, the broadcasters’ NextGen TV group, is certifying stripped-down boxes priced at $60 or less: old and new channels, 4K HDR, no internet needed, live TV only. Prototypes from ADTH, Skyworth and Zinwell were shown in April 2026, and Pearl said in October that products are expected to be unveiled in early 2027. If all you want is to keep watching when old signals end, that’s the box to wait for, and there’s time: the FCC hasn’t set a shutoff date (where the decision stands).
Questions
Should I buy a ZapperBox or an ADTH box?
Buy the ZapperBox if you want a real DVR or NextGen TV on more than one TV. Buy the ADTH box if you want live TV on one TV for the least money, or your TV has no HDMI input. If you only want to keep your channels when old signals shut off, wait: no shutoff date exists, and $60 basic boxes are expected to be unveiled in early 2027.
Do I need a converter box for NextGen TV right now?
No. Full-power stations that switch to ATSC 3.0 must keep an old-format version of their main channel on the air, and the FCC hasn't set a shutoff date. A box today is for 4K broadcasts, better reception or a DVR, not for keeping your channels.
Will a ZapperBox or ADTH box work on an old TV?
The ADTH box has a composite (red, white and yellow) output, so it can connect to TVs without HDMI, though reviewers found the picture on that output poor. The ZapperBox is HDMI only.
What about HDHomeRun or Tablo?
The HDHomeRun Flex 4K receives ATSC 3.0 but can't play encrypted channels, and more stations are encrypting. Current Tablo DVRs don't receive ATSC 3.0.
