What Is Station Bonding?

Station bonding is the deliberate interconnection of equipment chassis and conductive entry hardware to control voltage differences and provide defined fault, RF, and surge-current paths.

Start with the function: Station bonding is the deliberate interconnection of equipment chassis and conductive entry hardware to control voltage differences and provide defined fault, RF, and surge-current paths.

What the label leaves out

A wide, short bond can have lower RF and surge impedance than a long round wire even when both show near-zero DC resistance. The complete building bond still governs safety.

The mistake to avoid

Daisy-chaining chassis or running separate unbonded paths to different electrodes creates loops and dangerous potential differences.

A sound installation approach

Map the station and every entry, use a common entry/bonding architecture, preserve protective earth, use suitable conductors and hardware, prevent corrosion, and inspect periodically.

System boundary

Use current manufacturer documentation, measured RF behavior, the building grounding system, and applicable electrical and lightning requirements. A ratio, DC continuity check, or inline protective device does not establish complete-system safety or efficiency.
