A VHF Distributed Antenna System (DAS) is a specialized communication infrastructure designed to enhance and extend radio frequency coverage in the VHF range. VHF frequencies typically range from 136 to 174 MHz, and VHF DAS plays a crucial role in public safety communication, particularly for first responders and emergency services operating in large buildings, tunnels, or areas with limited coverage.
