2.2.2 Coaxial Cable Facts

Question 1

Coaxial Cable Components

Answer 1

• Two concentric metallic conductors
  
  • inner conductors is solid wire made of copper or copper-coated tin.
  • outer mesh conductor, or shield is made of aluminum or tin-coated copper.
• An PVC plastic insulator, which is surrounds the inner conductor and insulates the signal from the mesh conductor
• A PVC plastic cable sheath, or jacket that surrounds and protects the wire
