A coaxial surge protector limits specified transient stresses on an RF cable while supporting operation within a defined signal band. It belongs within a properly designed grounding and protection system.
How it works in practice
Different technologies have different frequency, DC-pass and discharge characteristics. Check the exact device's ratings and installation instructions. An RF power rating describes normal signal operation; it does not describe the energy of a lightning event. No single inline component establishes protection of the entire site.
Example and interpretation
An outdoor antenna cable may use a protector near its building entry as part of an engineered bonding arrangement.
Checks before use
- Check RF and DC requirements
- Read surge ratings
- Plan bonding
- Follow installation instructions
Important limit
Do not describe a protector as guaranteeing survival of every lightning event.
