Digital fibre DAS, VHF 162–163 MHz, 37 dBm RC-DAS-024
In the telecommunications industry, a VHF Optical Distributed Antenna System (DAS) is a fiber-optic-based signal distribution solution designed to extend and enhance Very High Frequency (VHF) band coverage—typically in the 136–174 MHz range—across large, complex, or shielded environments.
| UHF Frequency Range | 136-174MHz |
|---|---|
| Device Gain | 45±2dB |
| Device Output power | UL: -10± 2 dBm, DL: 37 ± 2 dBm |
| RF connector | N/Female |
| Power customization | 2–20Watt |
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).
