Coaxial cables are electrical cables designed to transmit high-frequency signals with minimal interference, using a central conductor surrounded by insulation, shielding, and an outer jacket. Their construction provides strong protection against electromagnetic interference (EMI), making them ideal for reliable signal transmission over varying distances. Coaxial cables are widely used for both analog and digital signal applications where signal integrity is critical.

Applications: Coaxial cables are commonly used in telecommunications, RF systems, antenna connections, broadcast equipment, internet/cable TV infrastructure, and test and measurement systems.

Selection requirements: Choosing a coaxial cable requires evaluating impedance (e.g., 50Ω or 75Ω), frequency range, attenuation, shielding effectiveness, cable type/size, and environmental durability to match the performance and installation needs of the application.

Common Coax Types:
• 75-ohm cables (RG-6, RG-59, RG-11): Video, TV, broadband
• 50-ohm cables (RG-58, RG-8, LMR): RF, antennas, communications
• Most common overall: RG-6 for consumer applications
• Best for long runs: RG-11 or LMR series
