Coaxial Cable Reliable Medium for RF Signal Transmission

Coaxial cable has a wide variety of uses as a transmission medium. It has four major parts: An inner conductor like a copper or copper clad aluminum wire that is the electrical signal’s carrier; An outer shield is made out of polyethylene or foam polyethylene and serves as the insulating dielectric; A foil braid of metallic shield that acts as protection against electromagnetic interference; And an outer jacket used for mechanical protection. Coaxial cables serve numerous purposes including television and radio frequency communication systems, and even certain industrial control systems. This type of cable can hold multiple frequencies, and has excellent shielding support making it ideal for long and short range signal transmission however, they perform poorly over great distances due to attenuation.
