Fibre DAS, VHF 162–163 MHz, 37 dBm RC-DAS-026
Railway communication networks face unique challenges: hundreds of kilometers of linear infrastructure punctuated by tunnels, deep cuttings, and underground stations where RF signals simply cannot penetrate. Train dispatchers, maintenance crews, and station operators all rely on VHF radio for safety-critical communications that must work flawlessly at every point along the route.
Also available for: VHF 136–174 MHz. The figures below are those of the standard model; we confirm the values of another band version in its build specification.
| Device Gain | 45±2dB |
|---|---|
| Power Customization | 2-20 Watt |
| Device Output Power | UL: -10±2dBm, DL: 37±2dBm |
| Frequency Range | 136-174MHz |
| RF Connector | N/Female |
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).

Description
The system's linear topology is purpose-built for trackside deployment. A centrally located master unit connects to the donor base station, then distributes optical signals to remote units positioned at strategic intervals along the route. Each remote unit—housed in an IP65-rated enclosure—withstands the vibration, temperature extremes, and humidity typical of railway environments, while fiber's inherent immunity to electromagnetic interference ensures signal integrity even adjacent to high-voltage traction power systems.
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.
