What is VHF (Very High Frequency) in DAS and ERRCS?

VHF (Very High Frequency) refers to the radio frequency range from 30 MHz to 300 MHz, commonly used for public safety, emergency responder communications, and two-way radios. In DAS (Distributed Antenna Systems) and ERRCS (Emergency Responder Radio Communication Systems), VHF bands—particularly 150-174 MHz—are used in rural areas, large campuses, and outdoor environments where longer-range communication is needed. While VHF signals travel farther in open spaces, they are less effective at penetrating buildings compared to UHF, which is why a properly designed ERRCS with VHF support is crucial for ensuring reliable in-building emergency communication.
