Understanding Air Dielectric Coaxial Cable Structure

Air dielectric coaxial cables are composed of three primary components: the conductor, shield, and air dielectric insulator. First, the conductor is typically made from copper or aluminum, responsible for carrying the signal efficiently. The material choice significantly impacts transmission performance, with copper known for its superior conductivity, ensuring minimal signal loss across long distances. Second, shielding plays a crucial role in protecting the signal integrity. By preventing external interference, materials like foil or braided copper provide effective electromagnetic shielding, thereby reducing signal loss. Finally, the air dielectric insulator, characterized by a low dielectric constant, ensures that the gap between the conductor and shield remains consistent. This design minimizes signal degradation, making air dielectric coaxial cables ideal for high-frequency applications.
