Understanding Coaxial Cables

What are Coaxial Cables?

Coaxial cables are essential for transmitting audio and video signals. They consist of a central conductor, insulation, metal shield, and an outer sheath. This structure can minimize signal loss and interference.

Basic Structure

Central Conductor: Usually made of copper, it carries the signal.
Insulating Layer: Surrounds the conductor to prevent signal leakage.
Metallic Shield: Provides protection against external electromagnetic interference.
Outer Sheath: Protects the cable from physical damage.

What are RG Ratings?

Understanding RG ratings is essential for selecting the right cable for your needs. These ratings indicate the cable's characteristics and performance capabilities.
