"Having the control voltage on the coax makes it possible to use with any transceiver. With the tuner remote, the antenna ideas are endless. Depending on antenna design, a Balun or unun may be needed also, inline with the antenna. The build quality seems to be solid. At home or portable I think it’s a good option."
"I needed a good tuner for my 73’ wire I snuck into my apartment attic. The URT1 seemed like a perfect fit. When I received it I was blown away how solid the tuner was! Built like a tank. Hooked it up and honestly the rest is history. I’m running a IC-7300mk2 and added the Click2Tune from Sota and makes tuning simple and no mistakes. I always run 30 watts max for digital so this should last my lifetime! 73 Bill N1LRM"
"The CHA URT1 is built fairly tough though I doubt water resistant or water proof. For the money, there are better (smaller, lighter, cheaper) tuners that can be rigged into a water tight Pelican case for environmental protect, battery power, and physical durability."
"I use my tan URT-1 mounted on a portable Will-Burt Expedition series mast w/EZ Raze at 30 feet and coax feed a 25 foot telescopic whip with 11, 16. 5, 33 and 42 foot fanned counterpoises, a 20M Delta loop beehive fed at the 30 ft apex and coax fed dual 25 foot whip V dipole. So far, this tuner has tuned everything I have tried. I think it is a good investment. Funny thing, my URT-1 has the labeling oriented so that the beehive connection is up. I like that this unit is Chameleon rugged."

"Good delivery. The product has nit been tested yet."
"With a 25 ft vertical radiating element and a 16ft radial hanging vertically from our deck it tuned ham bands between 10m through 80m and made several contacts hunting 20m POTA. A choke was used at the coax to tuner connection."
"Really well constructed. Has worked as advertised and is a great addition to my low power activities. 👍🙂"
"I have not used the tuner in anger, but I have hooked it up with a fairly easy load (42’ and 8. 5’, fed through a 4:1) and it tunes up 80-10 just fine. The documentation, however, describes some other revision of the control box (one that doesn’t have a “complete” led), and it’s totally unclear what that led even means. It’s not what you would like, which is a led that lights when a tuning sequence begins and extinguishes when it ends (either by succeeding or giving up). It just seems to flash when the tune button is released. I thought that it might flash when the tuning sequence ends, but I have never seen a delay before the flash, even when I do deliberate things to force what should be a long tuning sequence."
"The URT-1 makes a good Chameleon Antenna a great antenna. As a big fan of tuners at the antenna, the URT-1 makes it easy to do at home or in the field. I power mine from Anderson power poles on my go-box and can carry the tuner, controller (bias-T) in my Chameleon sling pack with components of the Tactical Delta Loop. How nice to get nearly 1:1 SWR from 75m through 10m!"
URT1 · Universal Remote Tuner
Put the matching network at the antenna feed point—where it can reduce loss in the coax between the tuner and the antenna.
Why operators choose it
The CHA URT1 separates the indoor coupler from the outdoor tuner and carries RF, DC power, and control over the same coaxial run. That places the tuner close to the feed point, keeps the operator-side installation simple, and gives portable, HOA, EMCOMM, and fixed-station operators a practical way to work with several documented antenna configurations.
It is not a universal promise that every wire will tune on every band. Radiator length, counterpoise, feed-line length, installation geometry, and the impedance presented to the tuner still matter. Start with one of the documented URT1 antenna paths and verify the completed system at low power.
Quick product reference
System limit: The lowest applicable rating of the tuner, BALUN, feedline, connectors, and completed system controls.
Before you deploy
The URT1 is one part of the antenna system. Choose the radiator, return path, feed line, mounting, and operating limits together.
The URT1 can be used with several vertical, wire, and balanced-feed arrangements, but each path has different radiator, counterpoise, feed-line, mounting, and tuning requirements. The handbook compares those paths in plain language before you buy or deploy.
The applications guide provides field layouts for the principal URT1 configurations. Confirm the current User Guide before changing connections or operating limits.

Documented configuration guide
Choose the antenna family and feed method that match your operating objective. Each path below comes from the June 12, 2026 Applications Guide and remains subject to the current URT1 operator manual and product-specific instructions.
Coaxial-fed antenna
Connect the antenna feed line to the Tuner Unit’s ANTENNA connector. Leave the top Beehive connector unused.
Single-wire or direct-fed antenna
Connect the radiator as documented and provide the required ground or counterpoise at the Ground connector. Leave the ANTENNA connector unused.
Showing all 10 documented application paths.
Place the Tuner Unit at or near the antenna feedpoint to keep the high-SWR portion of the system short, or use it locally when the application requires an indoor tuner.
Use the weather-resistant Tuner Unit outdoors at the radiator end for an EFRW, long wire, ground-mounted vertical, or another specifically documented single-wire application.
Replace the broadband matching transformer with the URT1 and optional URT1 MB to create a remotely tuned portable vertical using the documented whip, mount, and return-current system.
Use the MPAS 2.0 antenna wire as a remotely tuned end-fed configuration with the URT1 at the feedpoint and the return-current path required by the selected geometry.
The guide presents a remotely tuned 80–6 m BV path that removes routine whip-length and loading-coil adjustment from the deployment procedure.
Add the URT1 at the feedpoint side of the documented TDL HYBRID configuration to reduce high-SWR feed-line loss while retaining the matching transformer.
Replace the matching transformer with the URT1, URT1 MB, and Blank Adapter for the guide’s directly tuned TDL configuration.
Replace the matching transformer with the URT1 to create a remotely tuned end-fed random-wire application using the selected EMCOMM radiator and documented return-current path.
Replace the SKYLOOP matching transformer with the URT1 at the feedpoint for the guide’s remotely tuned horizontal loop path.
Install the Tuner Unit near the rear antenna mount and the Coupler Unit near the operator for a compact remotely tuned vehicle antenna.
