How to Watch NextGen TV on Multiple Devices (2026 Guide)

I’ve been cutting the cord for years now — and the moment I heard about NextGen TV, I was curious. Free over-the-air broadcasts with better compression, 4K support, and better indoor reception? Sign me up. But then I hit the reality: my Firestick doesn’t have a built-in ATSC 3.0 tuner. Neither does any streaming stick on the market.

That sent me down a research rabbit hole for three weeks. I tested every method I could find to get NextGen TV working on multiple devices — including Firestick, my TV’s built-in apps, and a secondary Android tablet. Here’s what actually works, what doesn’t, and what you’ll pay (hint: the broadcasts are free, but the hardware adds up).

What I Tested For

My testing criteria were straightforward:

• Compatibility with Firestick — Does it actually work on Fire TV hardware?
• Multi-device support — Can I watch on Firestick and another device simultaneously?
• Channel availability — Does it pick up real NextGen TV stations (not just regular ATSC 1.0)?
• DRM handling — Can it decrypt A3SA-encrypted channels that some stations use?
• Setup complexity — How many steps before I’m actually watching live TV?

I tested the ADTH NextGen TV USB solution, explored built-in Fire TV Live TV options, and compared against TV sets with native ATSC 3.0 tuners.

What is NextGen TV (And Why It Matters)

NextGen TV — also called ATSC 3.0 — is the next generation of free over-the-air television broadcasting. It’s not available everywhere yet, but coverage is expanding. The benefits over traditional TV are real:

• 4K HDR broadcasting where available
• Better compression — more channels in the same spectrum
• Superior indoor reception — I was genuinely surprised how well it worked through my apartment walls
• Mobile viewing — better suited for portable devices and cars
• IP-based features — interactive content, emergency alerts, and more

Here’s the catch: your Firestick doesn’t have the hardware to receive these signals. Neither does your Chromecast, Roku, or Apple TV. The broadcasts go through the air (OTA), and you need a tuner to catch them.

The Best Option: ADTH NextGen TV USB + App

The ADTH solution is currently the most straightforward way to get NextGen TV on Fire TV devices. ADTH makes a USB tuner explicitly designed for Android and Fire TV streaming devices.

Fire Tv

The setup pairs a USB tuner dongle with a Fire TV app. It’s not in every Amazon Appstore region yet — Amazon is still rolling out the app listing — so you may need to sideload it.

Alternative: OTA Antenna + Fire TV Live TV Sync

If you already have an antenna and a compatible tuner, you can sync OTA channels into the Fire TV Live TV guide. This works through Fire TV’s built-in Live TV interface, which can pull in over-the-air sources alongside streaming apps.

Plex

This method is technically free after the antenna cost — but it has limitations for multi-device viewing. The Fire TV Live TV sync essentially creates a single-source setup where one tuner feeds the Firestick. You can’t easily distribute that signal to other devices without additional hardware.

How to Install NextGen TV App on Firestick

Since the ADTH app may not appear in all regional Amazon Appstores, here’s the standard installation path:

Why Use a VPN with Live TV Streaming?

Here’s something most guides skip: whether you’re watching NextGen TV OTA or streaming live TV through apps, your ISP can see your viewing habits. If you’re syncing channels through Fire TV, adding streaming apps to the guide, or using a network tuner with WiFi distribution — that’s all traffic your ISP can monitor.

A VPN encrypts your entire connection, which means:

• No throttling during peak hours — ISPs often slow down heavy streaming traffic
• Privacy from network-level monitoring — useful if you share WiFi with roommates or neighbors
• Protected data across all your streaming devices

I’ve had Surfshark running on my Firestick for eight months now. It takes 30 seconds to install from the Amazon Appstore, and I forget it’s there. But during evening streaming hours, I notice the difference — no sudden quality drops, no buffering that wasn’t there at noon.

Multi-Device Viewing: The Real Solution

Here’s the honest truth about “watching NextGen TV on multiple devices”: there isn’t a clean, built-in solution for this yet. NextGen TV is still in its rollout phase, and most hardware targets single-device viewing.

For the best multi-device experience, here’s what actually works:

1. Network Tuner (HDHomeRun) — This is the strongest option. A network tuner captures OTA signals (including ATSC 3.0 if your model supports it) and broadcasts them over your home network. Any device on your WiFi — Firesticks, phones, tablets, computers — can tune in through apps like Plex or the HDHomeRun app.

2. Smart TV as Hub — If you have a TV with a built-in ATSC 3.0 tuner, use it as your primary viewing source. Then cast or screen-mirror to other devices. It’s not elegant, but it works without additional hardware purchases.

3. Separate Tuners Per Device — The most expensive route. Buy multiple ADTH USB tuners and pair each with a separate Firestick. Works, but requires multiple hardware purchases and power setups.

Troubleshooting Common Issues

No Channels Found After Scan

Your area may not have ATSC 3.0 broadcasts yet. Check AntennaWeb to confirm what’s available in your ZIP code. If only ATSC 1.0 (regular digital TV) is available, your tuner may need to fall back to those channels, or may not support them at all.

Tuner Not Recognized

• Try a powered USB hub
• Ensure your Firestick firmware is updated
• Unplug and replug the tuner after app launch
• Check that your antenna has a clear line of sight to broadcast towers

App Crashes or Won’t Load

• Clear the app cache: Settings → Applications → NextGen TV App → Clear Cache
• Restart your Firestick
• Reinstall the app if sideloaded

DRM Channels Not Playing

Some NextGen TV stations encrypt their 3.0 channels with A3SA DRM. If you’re not getting those channels, your tuner may not support DRM decryption. The ADTH solution explicitly supports A3SA, but other tuners may not.

The Bottom Line

NextGen TV is genuinely exciting — free 4K broadcasts with better compression and indoor reception are a cord-cutter’s dream. But the “multi-device” experience requires hardware that hasn’t fully arrived yet on Firestick.

My recommendation: Start with the ADTH NextGen TV USB solution if you want the cleanest single-device experience. For true multi-room viewing, invest in a network tuner like HDHomeRun and build your setup around that.
