VHF



Our VHF Simplex Distributed Antenna System (DAS) for railway tunnel applications offers enhanced communication, safety, and monitoring capabilities within tunnel environments. By extending radio signal coverage, improving signal quality, and facilitating swift emergency responses, VHF DAS systems ensure reliable communication channels for railway personnel and emergency services.
