How this exact system works
Power down, lower the antenna, inspect and label matching link positions, examine wire and insulation, then pack both legs and the feed point as one known system.
The boundary that prevents mistakes
This is not LINK-D with an extra band and it is not simultaneous multiband hardware. Do not hot-switch or infer compatibility from shared BNC and terminal hardware.
Use this field sequence
Quarantine damaged parts, label settings and matched components, update the kit inventory and field record, and do not return the system to service until the exact fault is corrected.
