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.
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.
For users operating with GMRS, the frequency range of the RT97L is:
This range allows for effective communication and operation in the designated GMRS frequencies, which are crucial for users who need clear, uninterrupted signals.
The RT97L portable gmrs repeater is designed with flexibility in mind. By connecting the repeater to a Raspberry Pi via its DB-9 interface, users can expand the repeater's functions. This allows for easy programming and the ability to customize the repeater to fit specific needs, whether you’re operating in a particular area, enhancing security, or fine-tuning performance.
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.
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.
The RT97L is capable of storing 16 different channels, which means it can quickly switch between up to 16 communication frequencies.
The duty cycle for RT97L repeater is 100%.
RT97S base station comes with a DB-9 port, which can be directly connected to the included speaker mic and is compatible with Raspberry Pi.
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.
Yes, the RT97L repeater is compatible with GMRS handheld radios that are repeater capable.

Outstanding range. I used it for a large outdoor event, and it covered the entire area effortlessly, providing clear communication all day.
Perfect for outdoor adventures. Took it camping, and it kept us connected across miles of wilderness. Highly recommend for off-grid setups.
Out of box, the repeater was ready to go. It was easily to get my handheld radio programmed and working with RT97L. Perfect bundle for me.
Works great may have to get one more to cover all the nooks and crannies in our 60 square mile mountain ranch. Highly recommended.
If you want high power and long coverage, and you want to setup easily, this will be your device. I have no background in radio and this was super easy for me to setup.
This unit is well made and an upgrage from RT97S, which i have used for two years and it works great. Wish the RT97L also work well.
Have several problems with the software, they are solved quickly by Retevis. Now the software has been upgraded. Great product and service.
They are compact and very easy to set up. Have used them for my farm, they worked very well.
Easy to set and install. Keep in mind that the height of antenna is important.
As advertised. Good quality and great value of paired with proper antenna. I will keep tracking of the performance.
This repeater was a breeze to set up. Plug it in, hook up the antenna, and it’s ready to go. It’s perfect for quick deployments.
I’m with a preparedness group called Anderson Island Prepares on a small island in Puget Sound. Currently, we’re using Ailance HAG 1 radios, and we’re looking to upgrade to a 25W repeater. We’ve got a 5W repeater in the group now, which works well, but we could definitely use more power to improve communication between our island and others in the area. The RT97L looks like a promising option with its 25W output, and we’re hoping it’ll help us extend our range and ensure better connectivity with neighboring islands.
I get 20 miles out of the 10 watt rt97s with high quality LMR400 and a high gain comet antenna mounted 37 feet up. The L should get more. Expect it
The new RT97L model is pushing 18+ watts past the duplexer—huge upgrade!
With the 10W RT97S repeater, I can easily get 10 miles on a handheld. Simplex range around here is about 2 miles, but I’ve had base stations connect from as far out as 20.1 miles using their base setups. Can’t wait for the new 25W RT97L to ship!
I have this RT97S set up and it works great.
We have access to grain elevators with about 150 feet of elevation, which should help maximize the range of our repeater. The RT97S’s performance in both rural and elevated locations makes it an ideal candidate for our setup.
Our goal is to create a reliable communication network for locals, and the RT97L’s GMRS capabilities, combined with its ease of use and installation, make it a strong contender for the job. Looking forward to seeing how it performs!
We're planning to set up a community GMRS repeater in South Central Kansas, with the potential to expand later. The goal is to provide reliable communication in case of grid, cellular, or internet outages. The Retevis RT97L seems like a promising option for this project, given its 25W power output and durability.
Utterly fantastic! Long range and clear! If I ever need more, I will get these ones again.
