Coaxial Cable (RF)

Coaxial cable, often referred to as "coax," is a type of transmission line used for carrying high-frequency electrical signals, particularly in radio frequency (RF) applications. Its primary use cases include television broadcasting, internet connectivity (cable modems), and radio communication systems.

Coaxial cable's evolution has seen advancements in materials, construction, and performance. Early cables used air as the dielectric insulator, while modern versions use polyethylene or foam for better flexibility and lower signal loss. The introduction of shielded coaxial cables further reduced interference and improved signal integrity.

Key features of coaxial cable include its central conductor surrounded by an insulator, all enclosed within a braided shield and a protective outer jacket. Specifications like impedance, attenuation, and bandwidth are crucial for determining the suitability of a cable for a specific application.

The future of coaxial cable hinges on its ability to compete with newer technologies like fiber optics. However, coaxial cable remains a reliable and cost-effective solution for various applications, particularly in legacy infrastructure and niche areas where bandwidth requirements are less demanding.
