Cable Attenuation Explained

Introduction

This guide explains cable attenuation in RF systems and how to calculate it.

What is Cable Attenuation?

• Cable attenuation is the reduction in signal strength as it travels through a cable.
• It is typically measured in decibels per unit length (dB/m or dB/ft).

Factors Affecting Cable Attenuation

• Cable Type:
  Different cable types have different attenuation characteristics.

• Frequency:
  Attenuation increases with frequency.

• Cable Length:
  Attenuation increases with cable length.
