Kirisun TR850 Tier 2 DMR Repeater
$4,594.25 inc GST
The Kirisun TR850 is a rugged Tier 2 DMR repeater in VHF or UHF, with up to 45 W output and mixed analogue and digital operation. Its 3U chassis leaves room for a duplexer and suits desk, cabinet or rack installs. Supplied, licensed and installed by Signals NZ, Kirisun’s exclusive New Zealand distributor.
The Kirisun TR850 is a Tier 2 DMR repeater for reliable single-site coverage or linked multi-site networks. It runs in analogue, digital or mixed mode and switches automatically depending on the type of call it receives, so analogue and DMR radios can share one repeater while you migrate your fleet.
Available in VHF (136–174 MHz), UHF low band (400–470 MHz) and UHF high band (450–520 MHz), this DMR repeater delivers up to 45 W (VHF) or 40 W (UHF) at a 100% duty cycle. The 3U chassis has room for a duplexer inside, making it a tidy all-in-one option for desk-top, cabinet or rack installation. Signals NZ is Kirisun's exclusive New Zealand distributor, so you get local support, programming and service from the team that brings the brand into the country.

Licensing & installation
Every repeater needs a licensed channel. Signals NZ handles the whole RSM licensing process for you: applying, coordinating frequencies, holding the licence and managing renewals. Engineered repeater channels typically take 1–4 weeks, depending on complexity.
We design coverage around how your team works, with site surveys, repeater modelling and on-site testing after installation. Once your network is live, our radio service team can monitor it in real time to spot and fix issues quickly, alongside routine maintenance.
Complete your system
Pair the TR850 with a Procom duplexer or VHF 4-cavity duplexer, a base station antenna and quality coax cable. Short on rack space? The 1U Kirisun DR600 is Tier 3 upgradable, and the next-generation Kirisun K-R600 adds 2048 channels and a built-in SIP gateway. For trunking, see the Kirisun DS6000 Tier 3 system.
