Basic principles

The basic idea is to protect equipment and people against lightning by conducting the lightning current to ground via a separate preferential solid path and reduce the electromagnetic field.

Well-proven basic principles are shielding (Faradays cage, armed concrete, screened cables), bonding and cabling.

Protector selection

Basic criteria for selecting a protector

• Bandwidth
• AC/DC powering via Coax
• Protection requirements (e.g. overvoltage pulses)
• RF requirements (RL, IL, PIM)
• Selection of gas discharge tubes
• Environmental requirements (e.g. outdoors)
• Dimensions
• Connector interfaces
• Requirements for installation and grounding
