Start here: A station needs coordinated protective grounding and bonding to reduce shock and surge hazards; RF return paths and common-mode control are separate design jobs.
Why this changes a real station
A safe installation ties equipment, cable entry, power service, and grounding electrodes together under current code so fault or lightning current does not create dangerous differences.
What it looks like in practice
A desktop ground wire may change RF symptoms, but it cannot substitute for the building grounding electrode system or correct antenna balance.
What to do next
Start by identifying safety earth, lightning bonding, equipment bonding, and RF-current paths separately; use qualified help where the building system is involved.
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.
