FAQ
The power gap matters most at range. With 5W, long-distance calls may come in weak or not at all. In contrast, 25W significantly improves signal range, allowing for clearer and more stable communication across large properties.
The factory output of the RT97L is between 22W and 25W. With the internal duplexer and feeder cable in the path, some loss occurs, so the actual output may range from 15W to 22W depending on the quality, thickness, and length of the feeder.
For GMRS operation, the RT97L transmits on 462.550-462.725 MHz and receives on 467.550-467.725 MHz. This split covers the designated GMRS repeater pair frequencies for clear, uninterrupted service.
The RT97L is built for flexibility. Connecting a Raspberry Pi to its DB-9 interface expands repeater functions, so you can program and customize the repeater to fit specific needs, from linked operation to sensor and alarm integration.
In receive mode the RT97L draws about 180 mA, and in transmit mode it draws about 5.5 A. These figures describe the working current of the repeater in each mode.
The RT97L is rated IP66, which means it withstands powerful jets of water from all directions. It performs well in harsh weather, though for optimal long-term performance it is best to keep it sheltered where possible.
Yes. The RT97L comes with an internal duplexer, which lets the repeater transmit and receive at the same time without interference and work efficiently with an antenna.
The RT97L stores 16 channels, so it can switch quickly between up to 16 communication frequencies as your team moves around the site.
The duty cycle for the RT97L repeater is 100%, so it can stay in continuous operation.
The main difference is that the RT97L is a 25W high power repeater while the RT97S is 10W, and the RT97L carries the IP66 waterproof certification.
Each RB26 runs full 3W on GMRS with 30 memory channels, including 8 repeater-capable channels, and 260 privacy codes. Handhelds talk directly at short range and reach the rest of your fleet through the RT97L when they move out of range.
Yes. The RB26 includes 8 GMRS repeater-capable channels, so it can be set to the RT97L repeater pair and communicate through the repeater, extending its 3W handheld range across the site.
Coverage depends on antenna height, terrain, and obstructions. One customer pairing a 50-foot tower with an elevated antenna planned a 50-mile radius across four North Carolina towns; wooded mountains need higher placement and can still leave shadows.
A USB programming cable for the RT97L is available as an accessory, so you can set repeater channels and CTCSS/DCS tones from a computer. The RB26 adds a wireless copy function that pushes settings from one handheld to the next for quick fleet setup.
Every RB26 charges on a USB charging base or through a Type-C USB cable from its 2000mAh Li-ion battery. For larger fleets, the RTC26 six-unit multi-charger is available as an add-on.
The kit comes in seven options: 2, 6, 10, or 48 RB26 handhelds, a six-charger bundle with 6 radios, and 4, 10, or 20 radio bundles that add the same number of speaker mics. Pick the count that matches your crew and add mics where vehicles need hands-free use.
The RT97L and RT97S are analog GMRS repeaters at 25W and 10W. The RT97P and RT97LD are DMR digital repeaters at 10W and 25W. Choose the GMRS models for standard US GMRS fleets like this kit, and the DMR models when your radios run digital.
School campuses and event crews running an RT97S report that the 10W duplexer leaves coverage gaps on large sites. The RT97L doubles the duplexer power to 25W in the same portable body, which makes it the direct upgrade path, and this kit adds RB26 handhelds in one order.
Installation takes four steps: open the silicone pad on the back, fix the bracket to the repeater with screws, drill a hole and insert the wall plug, then secure the repeater to the wall. After mounting, connect the FRP antenna and coaxial cable.
Large farms, ranches, construction sites, outdoor events, hunting camps, and open-air theaters. Recent inquiries cover a 150,000 sq ft warehouse with indoor dead zones, school campuses across several buildings, and marathon crews working in remote areas.
GMRS operation in the United States requires an FCC GMRS license, and the RB26 is FCC certified (FCC ID: 2ASNSRB26) with GMRS license required noted in its features. Buyers outside the US should confirm local regulations before ordering.
Yes, within GMRS rules. The RB26 operates on the standard GMRS band with 30 channels and 8 repeater-capable channels, so it works with repeater-capable GMRS radios from other brands and with GMRS repeaters set to the same frequencies.
