  • : ( )Cable

  • : ( )Coaxial cable1. Inner conductor2. Insulator surrounding the Inner conductor3. Metallic shield and outer conductor4. Outer insulating jacket Characteristic Few leaks of the electromagnetic wave to the outside. Able to bend. Able to transmit of a wide frequency range. Structure is complicated, and price is high.
