Coaxial cables are electrical cables designed to transmit high-frequency signals with minimal interference and signal loss. They consist of a central conductor, an insulating dielectric layer, a metallic shield, and an outer protective jacket. The shield helps prevent electromagnetic interference (EMI) and maintains signal quality.

Coaxial cables are commonly used for TV and satellite signals, cable internet, CCTV/security cameras, radio communications, networking, and other audio/video applications. They are available in different types and specifications, such as RG6, RG59, and RG11, depending on the application, frequency, distance, and required performance.

Key features:

Excellent protection against electromagnetic interference
Reliable transmission over relatively long distances
Durable and easy to install
Available with various connectors and cable sizes
Suitable for high-frequency analog and digital signals
