Connect the antenna's coax cable to the ANTENNA/RF port on the back of your Roku TV. Then run a channel scan from the Live TV settings. Once the scan finishes, Roku TV adds every channel it finds into the Live TV app. You then browse local stations in a normal channel guide.
In practice, the antenna connection is the easy part. Most delays come from skipping the channel scan, or expecting Live TV to appear on a streaming stick with no tuner at all. Roku TVs with a built-in tuner — Hisense's Roku TV lineup includes the R6, R7, and R8 series — handle the antenna signal directly. A separate Roku streaming device plugged into a dumb TV cannot.
The 30-Second Test: Do You Have an Antenna Input at All?
Not every Roku product can take an antenna. Roku TVs — actual televisions, built by partners like Hisense and TCL — usually have a built-in tuner. They also have a port labeled ANTENNA or RF IN on the back panel. Roku streaming devices, like a Roku Stick or Roku Express, plug into HDMI instead and have no tuner at all.
Flip your TV around and look at the back panel. A round coax port near the HDMI inputs means you likely have a Roku TV with a tuner, so the rest of this guide applies directly. A small stick or puck with no coax port means you'll need a separate digital tuner or converter box between the antenna and the TV.
Setting up live channels means spending time in the TV's settings menu. That's often right next to the screen, so a missing or dead remote turns into a real problem fast. If you own a Hisense Roku TV and can't find the box remote, the HiRemote app can help. It turns an iPhone into a Roku TV remote over Wi-Fi, so you can run the scan from the couch instead of hunting for batteries.
Roku TV vs. Roku Streaming Device: Which One Can Use an Antenna?
The word "Roku" covers two very different products, and only one of them connects to an antenna.
| Setup | Built-in tuner? | Antenna works? | Where channels show up |
|---|---|---|---|
| Roku TV | Yes | Yes, plug straight in | Live TV app, in the channel guide |
| Roku streaming stick or box | No | Not directly | N/A — needs a separate tuner box |
| Antenna + digital converter box | External tuner | Yes, through HDMI | Whatever HDMI input the box is plugged into |
Method 1: Connect the Antenna and Run a Channel Scan
Screw or clip the antenna's coax cable into the ANTENNA or RF IN port on the back of your Roku TV. If it's an indoor antenna, stand it upright near a window rather than behind furniture or a metal TV stand.
Open your TV's settings and look for an Antenna, Live TV, or Channels section. The exact wording shifts between software versions and TV brands, so don't worry if it's not word-for-word. Choose the option to scan for channels, then wait while the TV checks every frequency your antenna can pick up. This can take a few minutes, and a slowly climbing channel count near the end is normal.
Before you scan, it helps to know roughly which stations should be available where you live. The FCC's DTV reception maps list the over-the-air stations broadcasting toward a given address. That's a quick way to confirm the scan actually found everything nearby.
Method 2: Watch Channels Through the Live TV App
Once the scan finishes, the TV saves every channel it found inside the Live TV app. Open it from the home screen, the same way you'd open Netflix or YouTube. You'll get a guide-style layout with channel numbers, usually alongside a short description of what's airing.
From here, watching an antenna channel works like cable used to. Pick a channel, and it plays live. There's no monthly bill attached to the channels themselves, since broadcast TV is free — you only pay for the hardware. For more on what Roku can pull in this way, see our breakdown of whether Roku has local channels built in.
Fix 1: Antenna Is Connected but No Channels Show Up
This is almost always a signal problem, not a setup mistake. Move the antenna higher, away from walls with insulation or metal ductwork, then rerun the scan. Indoor antennas are especially sensitive to placement — even a few feet can change the result.
Check the cable connection too. A coax connector screwed on at an angle, or a cheap splitter between the antenna and the TV, can quietly weaken your signal enough to drop channels. Remove any splitter and connect the antenna directly to the TV while testing.
If the scan still comes back empty, confirm you're actually in range of broadcast towers for your area. Rural addresses, and homes surrounded by hills or tall buildings, sometimes just aren't in range, no matter how good the antenna is.
Fix 2: The Live TV App Is Missing or Grayed Out
No Live TV app on the home screen at all usually means one thing: the device doesn't have a tuner. You're on a streaming stick or box, not a Roku TV, and the 30-second test above already covers that case.
On an actual Roku TV, a missing or unresponsive Live TV app is usually tied to a pending software update. Tuner-related fixes often ship through regular firmware updates, so check for an update in the system settings and install it before trying anything else.
Method 3: Skip the Hunt for the Box Remote
Scanning for channels and browsing the guide both rely on the TV's directional pad. That's exactly when a missing or dead remote becomes a real problem. If your set is a Hisense Roku TV, the free browser-based Roku remote works from any phone or laptop on the same Wi-Fi. Type the TV's IP address, and the on-screen buttons start working — no app or account needed.
For something that sticks around permanently, the HiRemote app pairs with Hisense's Roku TV lineup (R6, R7, R8 series) in about 30 seconds over Wi-Fi. It adds number-pad channel input and a favorites list, on top of basic D-pad controls. It's free to download, and it doesn't replace the setup steps above — it just means a dead remote won't stall your scan.
Frequently Asked Questions
Do all Roku TVs have an antenna input?
No. Only Roku TVs with a built-in tuner have an antenna or RF IN port. Roku streaming sticks and boxes never do, since they rely entirely on HDMI. Check the back panel for a round coax connector before assuming your setup supports an antenna.
Why isn't my Roku TV picking up antenna channels?
Weak or no signal is the usual cause, not a setup mistake. Reposition the antenna away from walls and metal objects, remove any signal splitters, then rerun the channel scan. If the scan still finds nothing, your address may simply be outside range of local broadcast towers.
Can I watch antenna channels without using the Live TV app?
Not on a Roku TV. The Live TV app is where scanned antenna channels live, and there's no separate route to them. If your Roku product is a streaming stick instead of a TV, you'd need an external digital tuner box connected over HDMI, instead of the Live TV app.
Does a Roku streaming stick work with an antenna?
Not directly. Roku streaming sticks and boxes have no tuner and no antenna port, so they can't scan for or display over-the-air channels on their own. You'd need a separate digital converter box with its own tuner, connected to the TV over HDMI, with the antenna plugged into that box instead.
How do I rescan channels on my Roku TV?
Open the same Antenna or Live TV settings menu you used for the first scan, then choose the scan option again. Rescanning is worth doing after moving the antenna, after a storm, or whenever a channel starts dropping out. Broadcast signal strength shifts over time, so a channel that worked last month may need a fresh scan now.
Is Live TV on Roku free?
Yes. Watching channels you pick up with a physical antenna through the Live TV app costs nothing beyond the antenna itself, since broadcast TV doesn't carry a subscription fee. Some Roku TVs also offer separate, ad-supported channels inside Live TV that stream over the internet instead of the antenna.
