FAQ
The RT97S adds a DB-9 female connector for an external controller (for linking) and supports a speaker mic; the RT97 has no DB-9 port. Both are 5W full-duplex GMRS repeaters with a built-in duplexer. The RT97 offers 16 channels, while the RT97S offers 8 pre-programmed channels.
Yes. For more power, Retevis offers the RT94 (40W LTE & DMR digital repeater), the RT93 (25W), the single-band RT74 (20W), and the 25W GMRS RT97L. The 5W RT97 remains the most portable option in the family.
Because of FCC limits on FRS radios, the RT97 can only be used with GMRS radios, handheld or mobile. FRS radios cannot transmit on GMRS repeater input frequencies, so they cannot work through any GMRS repeater.
Yes. The RT97 is compatible with repeater-capable GMRS handheld radios from other manufacturers, such as BTECH, Radioddity, and Midland, as long as they can transmit on the GMRS repeater input frequencies (462.550-462.725 MHz).
No. The RT97 has a notch duplexer built into the housing, so there is no separate duplexer to buy, mount, or tune. Just connect a proper antenna and feeder cable and the repeater is ready.
Three options: the AC wall adapter at base, the 12V/24V vehicle cigarette-lighter plug on the road, or a solar battery setup off-grid. Both the AC adapter and the car plug come with the repeater.
Range depends mainly on antenna height, gain, and terrain. Mount the RT97's antenna as high and clear as possible - on a mast, rooftop, or hilltop - and a 5W repeater can cover from a few miles in rough terrain to tens of miles in open country.
Not waterproof. The RT97 uses a rugged, water-resistant housing adapted from cable TV amplifier enclosures, but it carries no IP rating. Mount it indoors or in a sheltered spot and keep the antenna outside for the best results.
The RT97P is the DMR digital model of this repeater family. Choose the RT97 for standard analog GMRS radios; choose the RT97P only if you run DMR digital equipment.
The base RT97 package includes the repeater, an AC adapter, and a 12V/24V car cigarette-lighter plug, but no antenna or feeder cable. Choose the 1 Pack + Antenna + Cable bundle on this page for a ready-to-go kit.
