In this episode of DAS Talk, Peter and Gil sit down with Mike Gitomer of RF Augmented to talk real-world DAS troubleshooting, public safety ERRCS, RF engineering, sweep testing, commissioning, and the mistakes that can make or break an in-building communication system. Mike shares his background across carrier networks, large venues, public safety DAS, OEMs, integrators, and independent RF consulting. The conversation dives into common field issues like bad connectors, backwards directional couplers, weak testing practices, poor donor antenna placement, jurisdictional differences, and why proper testing matters before a system is accepted. This episode is a must-watch for DAS installers, integrators, fire alarm contractors, low-voltage teams, AHJs, building owners, and anyone working around emergency responder radio systems. Topics covered: DAS troubleshooting Public safety ERRCS systems Sweep testing and CW testing Bad connectors and failed return loss Directional coupler mistakes AHJ requirements and jurisdiction differences Subcontractor quality control Stadium DAS and cellular optimization Why reliable radio coverage matters for first responders Need DAS / ERCES Training for Your Team?
