ETA Distributed Antenna Systems Technician (DAST) is an ETA International public-safety DAS credential. ETA's 2025 DAST competencies integrate the basic distributed antenna systems and antenna-installation concepts from DASI, then add robust technical service skills for safely testing, commissioning, maintaining, troubleshooting, and supporting in-building public safety distributed antenna systems during and after installation.
The DAST competency requirements emphasize International Fire Code (IFC), NFPA, UL, and Authority Having Jurisdiction (AHJ) rules; Emergency Radio Communications Enhancement Systems (ERCES); public-safety DAS annual recertification and five-year reoptimization; RF exposure; OSHA, PPE, lockout/tagout, seismic and weather safety; fiber handling and optical light hazards; National Electrical Code and National Electrical Safety Code cabling requirements; decibels, Watts to dBm, free-space path loss, and link-budget calculations. Candidates should verify current ETA DAST exam length, scheduling route, prerequisites, and maintenance rules before testing.
