The best conductor geometry, path, and components differ because lightning energy and HF operating current occupy different frequency and energy ranges. A long wire may appear to connect everything at DC while developing enormous voltage during a lightning impulse.
Lightning-protection priorities
- Intercept and route energy outside occupied space.
- Bond all electrodes and incoming services to reduce potential differences.
- Use a common entry area with appropriate protectors.
- Keep conductors short, direct, mechanically secure, and suitable for surge current.
- Protect coax, power, control, and data conductors.
RF-management priorities
- Provide the antenna’s intended current return.
- Maintain balance and control common-mode current.
- Bond station cabinets to reduce RF voltage differences.
- Keep matching networks and feed lines within voltage, current, power, and duty-cycle limits.
What no system promises
No arrestor, ground rod, disconnect switch, or bonding network guarantees personnel or equipment survival from a direct strike. Lightning protection reduces risk; it does not make operation during a storm acceptable.
