Start here: A single-point ground arrangement brings relevant station cables and bonds through one coordinated entry or reference point before they continue indoors.
Why this changes a real station
The goal is to limit voltage differences and give surge current a short, controlled route toward the bonded grounding system. Physical layout matters more than the label.
What it looks like in practice
A neat copper panel is not a single-point system if coax, power, network, or control cables bypass it elsewhere.
What to do next
Inventory every conductor crossing the station boundary, route protection through the common entry, and bond it under current electrical and lightning rules.
Evidence boundary
Keep frequency, reference plane, antenna geometry, losses, measurement method, and safety conditions attached to the conclusion. A match, a DC check, or one field symptom does not prove efficiency or identify the complete RF path.
