FAQ
We provide two kinds of coaxial cable: 15 m and 3 m. That gives you two kinds of GMRS repeater kit to choose from: the RT97S GMRS Repeater + 3 m coaxial cable + antenna, and the RT97S GMRS Repeater Kit with the 15 m cable.
The RT97S weatherproof enclosure is made of metal — a rugged cast-aluminum housing that stands up to the elements outdoors and helps dissipate heat during continuous operation.
Yes. The RT97S is easy to program and set up, and you don't need any special skills to get it running. Attach an antenna and cable, connect power, and it is on the air — perfect for beginners who want something simple.
The duty cycle for the RT97S is 100%, so it is built to run continuously.
The RT97S base station comes with a DB-9 port that connects directly to the included speaker mic and is also compatible with a Raspberry Pi for external control.
Yes. The RT97S supports DC 12-24V power, vehicle power supply, and solar charging (the solar panel is not included in the package).
The RT97S and Midland's compact repeater serve similar use cases. Retevis launched the RT97 family first, and Midland released its repeater afterwards; the two are close in capability. The RT97S focuses on plug-and-play simplicity, flexible DC/vehicle/solar power, an included USB programming cable, and Retevis lifetime technical and customer support.
Due to FCC limitations on FRS, this repeater works only with GMRS radios — both handheld and mobile GMRS radios.
Yes. The RT97S repeater is compatible with repeater-capable GMRS handheld radios, including models from other manufacturers such as BTECH, Radioddity, and Midland.
The main difference is that the RT97S has an extra DB-9 female connector for adding an external controller for linking purposes, and it can connect with a speaker mic.
The RT97S repeater has the same face shell and the same dimensions as the RT97P DMR repeater, which distinguishes both from the RT97. The RT97S also adds an extra DB-9 connector for an external controller for linking purposes, while the RT97P is the DMR digital model.
A GMRS repeater is a device that receives signals from one radio and retransmits them at higher power, allowing communication over a much larger distance. By placing repeaters at high points such as hills, rooftops, or towers, you can cover terrain that handheld radios alone cannot reach.
The MA09 is a high-gain omnidirectional base station antenna covering the GMRS band from 462-467 MHz. It is an easy match for the Retevis RT97 series repeaters, including the RT97S, and pairs well with a low-loss coaxial cable.
