Short answer: buy a Tablo if you want one box that does everything for about $100 with no monthly fee and you watch mostly on Roku, Fire TV or Google TV. Buy an HDHomeRun if you want more tuners, NextGen TV (ATSC 3.0) reception, or you already run Plex or Channels DVR. The catch nobody mentions up front: neither box can play the DRM-encrypted ATSC 3.0 broadcasts that a growing number of stations now send, so "4K antenna TV" is mostly marketing for both.
At a glance
Tablo vs HDHomeRun in one minute
| Cheapest good setup | Tablo 4th Gen 2-tuner, about $100 |
| Most tuners | HDHomeRun Flex Quatro or Flex 4K (4) |
| ATSC 3.0 | HDHomeRun Flex 4K only, unencrypted channels |
| Monthly fees | None required on either |
| Best for tinkerers | HDHomeRun + Channels DVR or Plex |
The real difference in one paragraph
Both are network tuners. You plug an antenna into the box, connect the box to your router, and every TV in the house watches antenna channels through an app. That's where the similarity ends.
Tablo is a finished product. Recording storage is built in (128 GB on the 4th Gen, roughly 50 hours of HD), the guide is free, and the app looks like a cable menu. You don't configure anything beyond a channel scan.
HDHomeRun is a tuner first and a DVR second. SiliconDust sells the hardware, gives you a free app, and lets you add a USB drive for recording. But plenty of owners never use SiliconDust's app at all. They point Plex, Channels DVR, Emby or Jellyfin at it, because the HDHomeRun is the most widely supported tuner in the hobby.
So the choice is really this: do you want an appliance, or a component?
Prices and specs side by side
List prices below were checked on the makers' own stores in late September 2026. Retailers discount both often, and the Tablo in particular has dropped to around $80 during sales.
| Model | List price | Tuners | ATSC 3.0 | Storage | Optional fee |
|---|---|---|---|---|---|
| Tablo 4th Gen (2-tuner) | $99.95 | 2 | No | 128 GB built in, USB drive optional | None |
| Tablo 4th Gen (4-tuner) | Check tablotv.com; varies | 4 | No | Built in + USB | None |
| HDHomeRun Flex Duo | $109.99 | 2 | No | Your USB drive | $35/yr premium guide |
| HDHomeRun Flex Quatro | $149.99 | 4 | No | Your USB drive | $35/yr premium guide |
| HDHomeRun Flex 4K | $199.99 | 4 (2 ATSC 3.0) | Yes, unencrypted only | Your USB drive | $35/yr premium guide |
If you use HDHomeRun with third-party software, add that cost too. Channels DVR runs $8 a month or $80 a year. Plex Pass, which unlocks Plex's DVR, was listed at $6.99 monthly, $69.99 yearly or $249.99 lifetime as of late 2025. Those are the real running costs of the "enthusiast" route.
Who the Tablo suits
Most households, honestly. If the goal is "watch local news and record Sunday football without paying for cable," the Tablo does it cheaply and without a learning curve.
It works best if your TVs already run one of Tablo's supported apps: Roku, Fire TV, Google TV and Android TV, Apple TV, iOS and Android phones, and some Samsung and LG sets. The app also mixes in free ad-supported streaming channels alongside your antenna channels, which is handy if your antenna reception is thin.
The trade-offs are real, though. Two tuners means two things at once: record two shows, or watch one and record one. Families with overlapping prime-time habits hit that ceiling. And some reviewers, PCWorld among them, have reported stability complaints with the 4th Gen software. Updates have improved things, but it isn't as polished as the marketing implies.
Out-of-home viewing is limited. The 4th Gen is built for use inside your home network. If watching your recordings from a hotel matters to you, check Tablo's current remote-access policy before you buy.
Who the HDHomeRun suits
Three groups get more out of an HDHomeRun.
Plex and Channels users. If you already have a home server, an HDHomeRun turns it into a proper DVR with commercial detection (Channels), better guide data and remote streaming. Channels DVR in particular is widely regarded as the best OTA DVR experience available, and it only works with HDHomeRun-class tuners. We cover the Plex route in using Plex with live TV sources.
Busy houses. Four tuners on the Quatro or Flex 4K means four simultaneous recordings or streams. That matters on NFL Sundays.
People in NextGen TV markets. The Flex 4K is one of very few network tuners that can receive ATSC 3.0 at all. It only works on unencrypted broadcasts, but where those exist you get Dolby audio and occasionally better picture.
The cost is complexity. You buy your own drive, and the free SiliconDust app is functional rather than friendly. A $35 a year premium guide adds series recording options many people will want.
The ATSC 3.0 problem
ATSC 3.0, sold as NextGen TV, is the newer US broadcast standard. It can carry 4K and HDR in theory, and broadcasters are turning it on market by market.
Here's the part that matters when choosing a box. Many stations encrypt their ATSC 3.0 signal with DRM. SiliconDust states plainly that its devices can't play DRM-protected NextGen broadcasts. Tablo doesn't receive ATSC 3.0 at all. In practice, most stations still simulcast the old ATSC 1.0 signal, which both boxes handle fine.
The only network DVR that currently plays encrypted ATSC 3.0 is the ZapperBox M1 (about $250 to $275, plus a $30 a year guide as of late 2025). It's a niche buy, and only worth it if a station you care about has dropped its ATSC 1.0 signal.
Our advice: don't pay the HDHomeRun Flex 4K premium for 4K. Pay it for the four tuners, and treat ATSC 3.0 as a small bonus.
What to skip
Don't buy either one before checking reception. A tuner can't fix a weak signal. Look up your address on the FCC's DTV reception map, and read our antenna guide first. A $40 antenna in the right spot does more than a $200 tuner.
Skip older Tablo models on clearance. The 3rd Gen and Dual Lite need a paid guide subscription, which erases the savings.
Skip the Fire TV Recast. Amazon discontinued it, and relying on a dead product's servers for your guide is a bad bet.
Don't run either box on weak Wi-Fi. Both are network devices. Connect the tuner itself by Ethernet cable to the router. The TVs can be on Wi-Fi, but an HD antenna stream runs roughly 8 to 19 Mbps per channel, so it adds up fast. Our bandwidth guide has the numbers.
The verdict by buyer
| If you are... | Buy |
|---|---|
| A couple wanting locals plus a few recordings | Tablo 4th Gen 2-tuner |
| A family that records a lot | HDHomeRun Flex Quatro, or 4-tuner Tablo |
| Already running Plex or a home server | HDHomeRun Flex Duo or Quatro + Channels DVR |
| In a strong NextGen TV market | HDHomeRun Flex 4K, knowing DRM limits |
| Losing an ATSC 1.0 station you need | ZapperBox M1 |
If you're weighing an antenna DVR against paid streaming, the cheapest ways to watch live TV and our overview of recording options put both side by side.
Quick answers
Does Tablo or HDHomeRun need a subscription? Neither requires one. Tablo's 4th Gen guide is free. HDHomeRun offers an optional $35 a year premium guide and DVR service.
Which has better picture quality? Both pass through the station's broadcast signal, so picture is essentially the same. Differences come from your antenna and your streaming device.
Can HDHomeRun record without a computer? Yes. Plug a USB hard drive into a Flex model and record through the free HDHomeRun app.
Does either support ATSC 3.0? Only the HDHomeRun Flex 4K, and only for broadcasts that aren't DRM-encrypted.
Can I use Tablo with Plex? Not officially. Plex's DVR is built around HDHomeRun-type tuners.
How many TVs can watch at once? One live channel per tuner. Recordings don't use a tuner, so several TVs can play recordings at the same time.
Is the Tablo 4-tuner worth it over the 2-tuner? Only if two people regularly record different shows at the same time, or you record sports while someone watches live.
Prices are list prices from the manufacturers' stores and change often, especially around sales events. ATSC 3.0 encryption varies by station and market. Checked September 2026.
