A city stream fails in layers. A crowded cell tower weakens the picture, a loose cable adds noise, heat drains a battery, and a heavy bag turns a long walk into a short broadcast.
Redundancy helps only when it is manageable. Combine connections where possible, carry a tested backup path, secure every cable, monitor audio continuously, and know how long the power system lasts under real load.
The best kit is not the largest one. It is the setup you can operate while moving, talking, navigating, and noticing the story around you. Reliability begins with fewer surprises and a practiced recovery plan.
