Description
FAQ
1. Will the speaker-microphone from the RT97S work on the RT97L?
Yes, the speaker-microphone for the RT97S and RT97L are compatible and can be used interchangeably.
2. What is the height and wind resistance rating of the RT97L antenna?
The RT97L antenna model is MA09, operating in the 462-467 MHz frequency range.
Height: 175 cm (approximately 5.74 feet)
Wind resistance: 50-60 m/s
Additional specifications:
VSWR (Standing Wave Ratio) < 1.5
Antenna gain: 7.2 dBi
Connector type: SL16-K
Material: Fiberglass
3. Can the antenna cable that came with the RT97S be used for the RT97L?
Yes, the 15-meter 50-3 Pure Copper Coaxial Extender Cable for RT97 will work with the RT97L. However, the RT97L’s antenna cable has been upgraded to 15 meters of 50-7 cable, which offers lower loss compared to the previous version.
4. Can I replace the SL-16 connector with an N-type connector on the RT97L?
Yes, the RT97L can be adapted to use an N-type connector. We recommend the following two options:
Use an adapter: This is the most cost-effective and preferred method. The adapter is inexpensive and ensures no signal loss.
Replace the connector yourself: If you choose to replace the connector, please ensure that you use coaxial cable with an outer diameter of 4mm. Be cautious, as improper replacement can damage the paint and affect the waterproofing.
5. Will the RT97L operate on all 16 GMRS channels?
The RT97L is pre-programmed with 16 GMRS channels, all set according to GMRS standards. The device includes dedicated GMRS repeater frequency points, ensuring full compliance with regulatory requirements. To enhance convenience, the first 8 channels are set for wideband operation, while the remaining 8 are set for narrowband operation. This allows users to easily switch between the two bandwidth settings without needing additional programming.
6. RT97L repeater programming software has a problem when writing frequency?
When you click "Read", a password input box will appear. You can directly click "close" to ignore it, or input 288288.
If you want to set a password, click "write", the first "password" is 288288, then enter your "New Password".
7. What is the difference between 5W and 25W?
The difference in power can be significant. For example, using 5W of power, communication over a long distance might result in weak or no signal. However, with 25W of power, the range can greatly improve, allowing for clearer and more reliable communication over much longer distances.
While power is crucial, factors like antenna height also play an important role. In situations where elevation isn't favorable, higher power can be a big help in extending communication range.
8. Is the actual output power really 25W?
The factory output is between 22W-25W. However, when operating with a duplexer, there may be power loss, reducing output to around 15W-22W, depending on the quality, thickness, and length of the feeder cable.
9. What’s the GMRS Repeater Frequency Range (TX and RX)?
For users operating with GMRS, the frequency range of the RT97L is:
- TX (Transmit): 462.550 - 462.725 MHz
- RX (Receive): 467.550 - 467.725 MHz
This range allows for effective communication and operation in the designated GMRS frequencies, which are crucial for users who need clear, uninterrupted signals.
10. What Is Amp Absorption in TX and RX?
- Receive Mode Absorption: 180mA
- Transmit Mode Absorption: 5.5A
11. How is the RT97L Waterproof Even if the Doors Are Uncovered?
The RT97L gmrs mobile repeater is rated IP66 waterproof, meaning it can withstand powerful jets of water from all directions. This rating ensures that it performs well even in harsh weather or environments with heavy water flow. However, to ensure optimal performance and longevity, it's always a good idea to install the repeater in a protected location, especially in areas with extreme weather conditions.
12. Does the RT97L Have an Internal Duplexer?
Yes, the RT97L portable repeater comes equipped with an internal duplexer, which is essential for enabling the repeater to work efficiently with an antenna. The duplexer allows the device to handle both transmit and receive signals simultaneously without interference.
13. How Many Channels Does the RT97L Have? And What Does It Mean?
The RT97L is capable of storing 16 different channels, which means it can quickly switch between up to 16 communication frequencies.
14. What is the RT97L's Duty Cycle?
The duty cycle for RT97L repeater is 100%.
15. Does this repeater work with your handheld FRS units? Or just the GMRS radios?
Because of the limitations on FRS by the FCC, this repeater can be only ued for GMRS radio, no mater handheld GMRS radios or Mobile GMRS radios.
16. Is this repeater compatible with other manufacturers handheld GMRs radios that are repeater capable? For example BTECH, Radioddity, Midland?
Yes, the RT97L repeater is compatible with GMRS handheld radios that are repeater capable.

The IP66 waterproof rating is no joke. We got caught in a downpour during a camping trip, and the RT97L kept working flawlessly. Peace of mind for any outdoor adventure.
Set this up as a base station for our farm. The long-range signal coverage lets us communicate from the far pastures back to the house clearly. The three charging methods are very versatile.
Crystal clear audio even at the edge of its range. The 25W high power makes a huge difference compared to our old handhelds. It's like having a cell tower in your backpack.
Took it on a multi-day off-roading trip. Switched to low power when camped to conserve battery, then high power on the trail. The flexible power switching is a smart feature.
Perfect for our volunteer search and rescue team. We can quickly deploy it as a temporary communication hub in the field. The lightweight and portable design is key for our operations.
The backlit LCD is a lifesaver for nighttime operations. I can easily check the channel and settings in the dark. Simple, thoughtful design.
Mounted it permanently in my cabin. Now my family can use simple GMRS radios to talk for miles around. It solved our communication problem in this cell-dead zone.
Survived a dusty construction site for months. The build quality is solid. This is clearly an industrial-grade piece of kit, not a toy.
Used during a charity bike rally. The repeater linked riders, support vehicles, and checkpoints over 20 miles. Flawless performance that kept everyone safe and coordinated.
As a park ranger, reliable comms are vital. The RT97L gives me a powerful, waterproof, and go-anywhere repeater to extend coverage in remote areas of the park.
I run a landscaping business. This keeps my crews in touch across large properties. The signal penetration through trees and hills is impressive.
Great value for the power and features. Compared to other GMRS repeaters, the RT97L offers professional performance at a very reasonable price point.
Easy to pair with our existing Retevis GMRS radios. No compatibility issues. It truly extends the signal coverage as advertised.
Used it to create a communication link between two buildings on our property. The signal is strong and clear. Solved our inter-building radio dead zone problem.
Perfect for event coordination. We used it for a marathon, connecting aid stations across the city. The consistent signal was critical for medical and logistics teams.
I love the option for in-vehicle charging. I can power it from my truck's battery while mobile, making it a true mobile base station.
The customer service from Retevis was excellent when I had a setup question. But the product itself is so intuitive, I hardly needed it.
