700/800MHz public safety repeaters extend dual band radio coverage for DMR, LMR and other mission-critical networks that operate in the 700 and 800 MHz ranges. They amplify both bands in one unit, so a single installation can serve users on either band inside buildings, tunnels and areas with weak outdoor signal.
According to their datasheets, the repeaters are intended to solve poor signal coverage in public safety networks, and the fiber optic system extends and improves 700/800 MHz DMR and LMR coverage. Exact ratings are listed in each datasheet.
The 700 and 800 MHz ranges are often shared with other services. Therefore, high selectivity filtering helps a repeater amplify only the intended frequencies and reject strong signals close to the band. This protects both the served network and its neighbours.
Mini repeaters suit small rooms and single floors. Power repeaters serve medium buildings, while the 40 dBm model covers larger areas or outdoor zones. For very large or multi-level sites, the fiber remote unit distributes the signal over optical fiber. In addition, check the donor signal level, because it determines how much gain the repeater can use.
For other bands, see 800MHz TETRA DMR repeaters and VHF BDA, or return to all TETRA and DMR coverage solutions. Read our in-building coverage planning guide for the full process.
Several 700/800 MHz products are specified for P25 as well as DMR and LMR. Check each datasheet.
Yes. The dual band models in this group amplify both ranges in one unit, which simplifies installation compared with two single band repeaters.
