Digital fibre DAS, VHF 162–163 MHz, 37 dBm RC-DAS-025
In emergency situations, communication failure is not an option. Firefighters, and paramedics operating in high-rise buildings, underground parking garages, and large public venues depend on uninterrupted VHF radio coverage to coordinate rescue efforts and ensure personnel safety.

Installation needs the agreement of the operator of each network carried (mobile operators, TETRA radio network): in Belgium and most other EU countries, a repeater or DAS may only carry a network with that consent. We deliver for projects where this agreement is in place. While it is being requested we can quote, and we prepare with you the technical information each operator asks for (bands, gain, output power, location).

Features
- Single master unit manages up to 8 remote units for multi-site coverage.
- Low noise figure (≤6dB uplink) preserves voice clarity in challenging RF environments.
Description
The system seamlessly integrates with existing Land Mobile Radio (LMR) and P25 infrastructure, converting RF signals to optical for transport over single-mode fiber. This architecture enables centralized dispatch centers to manage geographically distributed remote units covering up to 10 kilometers, ensuring first responders maintain clear voice communications regardless of their location within the coverage zone.
Figures are those stated for the standard model. Bands, power and options can differ per build: for your project we confirm them in a written build specification, and every unit ships with its own test record. Datasheets are available on request.
