Where Should a Coaxial Surge Protector Be Installed?

N-type coaxial surge protector with CentronRF watermark

Follow the protector and site installation design, including the required bonding location and conductor arrangement. Placement affects how surge current is diverted.

How it works in practice

A protector often belongs near the cable entry or another specified bonding point, but installations differ. Keep the prescribed bonding path short and direct, with suitable connections. Local electrical requirements and the site's grounding system should govern the final arrangement.

Example and interpretation

An inline protector floating on a cable without the specified bond cannot be assumed to provide its intended protection.

Checks before use

  • Read the installation guide
  • Identify the bonding point
  • Plan cable routing
  • Have the installation checked against applicable requirements

Important limit

Do not copy a generic layout without checking the site's grounding design.
