The 6 Best IR Remote Extenders
Updated by · How we research
Range, device count, carrier frequency and power separate these six wired and wireless IR remote extenders. The Sewell BlastIR Wireless Pro comes out on top. When users buy our independently chosen editorial recommendations, we may earn commissions to help fund the Wiki.
An IR remote extender can't help a remote that uses radio or Bluetooth, such as the Roku voice remote. For infrared remotes, it carries the signal to gear behind cabinet doors, in a closet or in another room. Wired kits run a receiver eye to stick-on emitters, and wireless kits relay the signal by radio.
From the manual
- Power goes into the back of each puck; the manual warns that the front IR-cable jack is easy to mistake for the power port. p. 2
- Receivers talk only to emitters on the same zone. Zone 0 reaches older BlastIR Wireless units, and Sewell says to reset after changing zones. p. 7
- The reusable AirStick pad is made to leave no residue; the 3M pads are permanent. Line up the pad's hole with the zone dial. p. 6
- A receiver light that stays blue means interference, most often from a mesh Wi-Fi network. Move the unit or switch both to another zone. Sewell troubleshooting
Why the Sewell BlastIR Wireless Pro is our top pick
Our pick reaches rooms a cord can't, and it still handles the closed cabinet. Its two pucks talk by radio in the 915 MHz band, rated for 650 feet and less through walls and closed doors.2 Our runner-up, the Cable Matters 203002, is one wired cord sold in lengths up to 25 feet,3 so reaching another room means a cable run through the wall.
The receiving end is more forgiving too. The BlastIR's receiver is rated to catch a remote from about 30 feet and passes carriers from 20 to 60 kHz;2 the cord wants the remote within 15 feet and 30 degrees of its bulb and covers 30 to 60 kHz.4 On the sending side, our pick has a built-in emitter plus a split cable for two more devices,1,2 and a dial with ten zones keeps several kits in one house from crossing signals.1
The cord wins on simplicity: there's nothing to pair or set, and it costs much less. For one box behind a cabinet door it does the job, as long as it runs from a wall charger, since a TV's USB port shuts off with the TV.3 Our pick needs power at both ends,1 and its maker lists three devices it won't control, including an Arris cable box.2

Editor's Notes
November 4, 2026, by Ezvid Wiki Editors:
We read Sewell's BlastIR Wireless manual and SIIG's quick start guide, checked each pick against its maker's pages or seller listings, and added a spec table and a closer look at why the Sewell leads. We corrected the TNP's emitter count and removed details we couldn't confirm: the SIIG's antennas and pickup angle, the ICESPRING's metal block and USB power, and the TNP's screw terminals. A 2021 note's claim that the BlastIR needs a line of sight between its units is corrected too.
October 15, 2026, by Ezvid Wiki Editors:
Handling a closed cabinet and a second room equally well keeps the Sewell BlastIR Wireless Pro on top, and its 10 channels let several kits share a house. Three picks from the early 2021 version, the BAFX 54-5EXN Repeater, the BAFX Repeater Cable and the StarTech IREXT2, are no longer available. We also dropped the BroadLink RM4 Pro S. It's a capable Wi-Fi hub, but it swaps your remote for a phone app instead of extending the remote you already have, so it belongs on a different list.
The Next Generation Remote Extender Plus, the SIIG CE-RC0111-S1 and the Cable Matters 203002 stay too, under their current model names. New are two wired kits for bigger setups: the ICESPRING IR Repeater System, with five dual emitters, and the TNP A-1204A, which also passes 56 kHz signals.
We stopped at six. The other kits we screened were unavailable, near copies of these, or had specs that contradicted themselves. We found no independent lab tests of current IR extenders, so the ranking rests on makers' range and carrier-frequency specs and manuals, Sewell's list of devices it won't control, owner feedback patterns and recall checks.
Earlier notes
January 22, 2021, by Chris Gillespie:
Depending on the distance the signal needs to be extended by, there are several methods to achieve the same result. For shorter distances or single device operation, a wired version such as the BAFX Repeater Cable should be sufficient. For longer distances, a wireless repeater like the Sewell Direct BlastIR will give you more range. [2026 update: the BlastIR Wireless Pro on today's list links its two units by radio, so they don't need a line of sight to each other; only your remote has to see the receiver.] By converting the infrared signal into a radio frequency, the Next Generation Remote and the SIIG Pro can send the signal over much greater distances and even allow devices to be controlled from other rooms or from outside.

While I favor wireless models for convenience’s sake, the PM5900 was comparatively expensive for its extension range of 100 feet, so I removed it. For the same price, you can get products with significantly better ranges, like the StarTech IREXT2 and two of the newer models I’ve added - the Sewell Direct BlastIR and Fourair Wireless. Plus, the PM5900 was struggling with lagging and other commonly-reported issues – not surprising since it was released more than a decade ago. I’m quite a fan of the BlastIR because of its channel system, which allows you to add many of these devices and set up a complex web of repeaters for multiple systems in your house if you want.
I also removed the HDTV HookUp IRS6A because, while it was the least conspicuous model of them all, the installation just isn’t worth the effort and convenience (unless you’re a good electrician), and the price doesn’t really do justice to the effort either (it’s about as expensive as some of the wireless models).
Some of the repeater boxes are still good, cheap options and they tend to be more responsive than the wireless options, though wireless models are just a lot more inconspicuous and less messy to deal with. For repeater boxes, I’ve left the likes of the Inteset Technologies IR3856EM and the Gefone Kit GIRE0108, as well as the BAFX 54-5EXN Repeater which are very good, responsive options, especially the last one (though you may need to hide them in your cabinet somewhere). I’ve also included a couple of the smaller and more conspicuous wired repeaters I could find - the BAFX Repeater Cable and Cable Matters 10-Foot Repeater.
Special Honors
Xantech IR Kits Xantech, part of Nice North America, makes installer-grade infrared receivers, connecting blocks and emitters, sold through AV dealers and distributors. Its DL85K kit pairs a small surface-mount receiver, which Xantech says works near LED, LCD and plasma TVs and under CFL lighting, with a four-port connecting block, four emitters and a 12-volt supply, with a stated range of up to 80 feet. xantech.com
Wired Or Wireless?
If you'd rather run everything from a phone or voice assistant, a Wi-Fi smart IR hub such as the BroadLink RM4 Pro learns your remotes' codes and sends them itself.
Every IR extender does the same basic thing. A receiver catches the infrared flashes from your remote where the remote can see it, and an emitter, sometimes called an IR blaster, repeats them right on top of the hidden device's sensor. What differs is how the signal travels between the two.
Wired kits run a cord. A simple cable like the Cable Matters 203002 links one receiver to one emitter, while connecting-block kits fan one receiver out to four to ten emitters for a full cabinet of gear. They need no pairing or radio link, and they cost little. They also work fine through closed cabinet doors, because only the receiver needs to face the room. Their limit is cable length, so reaching another room means running wire through a wall.
Wireless kits replace the cord with radio, usually on the unlicensed ISM bands around 433 or 915 MHz, which pass through doors, walls and floors. Most use an infrared pickup box near you and an emitter box near the gear. The Next Generation kit skips the pickup and puts its transmitter in your remote's battery slot. Treat quoted ranges of hundreds of feet as open-air figures; walls, floors and metal cut them down.
If you'd rather run everything from a phone or voice assistant, a Wi-Fi smart IR hub such as the BroadLink RM4 Pro learns your remotes' codes and sends them itself. That replaces your remote rather than extending it, and it needs Wi-Fi and an app.
Carrier Frequency And Compatibility
Infrared remotes don't just flash on and off. They pulse their light at a carrier frequency, typically 33 to 40 kHz or 50 to 60 kHz. The NEC format used by many Japanese brands runs at 38 kHz, and Philips' RC-5 and RC-6 formats at 36 kHz (Wikipedia). Most extenders pass the common 36 to 40 kHz range. If a cable box ignores a basic kit, look for one that lists 56 kHz too, like the TNP A-1204A, or a wide 20 to 60 kHz range, like the Sewell and SIIG kits.
The bigger trap is remotes that don't use infrared at all. Many streaming remotes, including the Roku voice remote and Apple TV remotes, use radio or Bluetooth, and no IR extender can repeat them. Some of those remotes still use infrared for TV power and volume, which is why the Next Generation kit lists some streaming remotes it supports and others it doesn't. To check a remote, point it at a phone camera and press a button: many cameras show an infrared LED as a faint flicker.
Read the incompatibility notes too. Sewell lists three devices its BlastIR kit won't control, and NextGen says its kit won't work with several Logitech Harmony models or with any universal remote that has a rechargeable pack or a large screen. A device that misbehaves with one kit may work fine with another.
Placement, Interference And Power
Put the emitter directly over the device's infrared window, not just in front of it (Biamp). If you can't see the window, hold a button that repeats, such as channel up, and slide the emitter around until the device responds, then stick it down. Cable Matters says to keep its emitter within about 5 inches of the device.
The receiver is the fussy part. Face it toward where you sit, not up at the ceiling, and keep it out of direct sun and away from bright lamps. Some lighting and screens put out infrared noise that can blind a receiver or trigger stray commands. LG warns that fluorescent lamp ballasts can interfere with its 38 kHz remotes (LG), and the ICESPRING seller tells buyers to keep its receiver away from plasma screens. If moving the receiver doesn't help, installer-grade receivers like Xantech's DL85 use noise suppression, and Xantech says they work near LED, LCD and plasma TVs and under CFL lighting (Xantech).
Most kits run on 5-volt USB or a 12-volt adapter. A TV's USB port usually switches off with the TV, so your extender would too; use a USB wall charger instead. These are low-voltage devices, and a November 2026 search of the U.S. Consumer Product Safety Commission's database found no recalls for any brand on this list (SaferProducts.gov).
How we researched this
We compared 14 current and former IR remote extenders and read the documents behind the six picks: Sewell's 12-page BlastIR Wireless manual and spec sheet, SIIG's quick start guide 04-1154A and spec table, Cable Matters' troubleshooting guide for the 203002, and NextGen's product, FAQ and warranty pages. ICESPRING and TNP publish no manuals we could find, so their details come from their sellers' listings. Background on remote signals and emitter placement comes from Wikipedia, LG, Biamp and Xantech. A search of the CPSC recall database on November 4, 2026 found no recalls for any of the six brands.

Frequently asked questions
Do IR extenders work through cabinet doors?
Yes. Put the receiver outside the cabinet where the remote can see it and the emitter inside, over the device's sensor. Wired and wireless kits both work this way.
Can an IR extender work through walls?
Wireless kits send the signal by radio, which passes through walls and floors at reduced range. Wired kits need the cable run through the wall.
Will an IR extender work with a Roku or Apple TV remote?
Only with remotes that use infrared. The Roku voice remote and Apple TV remotes use radio or Bluetooth, so an IR extender can't repeat their commands, though some still send TV power and volume by infrared.
What's the difference between an IR repeater and an IR blaster?
An IR blaster, or emitter, is the small part that sends infrared to a device. A repeater is the whole system: receiver, link and emitters. Smart IR hubs are blasters you control from an app.
Why does my IR repeater stop working when the TV is off?
It's probably powered from the TV's USB port, which usually shuts off with the TV. Plug it into a USB wall charger instead.
What can stop an IR repeater from working?
Common causes are an emitter that isn't over the sensor, a receiver facing the wrong way, sunlight or lamp interference, and remotes that use a carrier frequency or radio signal the kit doesn't support.
