➨Due to skin effect, catv cable is used in high frequency applications (> 50 MHz) using copper clad materials for center conductor. Skin effect is result of high frequency signals propagating along outer surface of the conductor. It increases tensile strength of the cable and reduces weight.
➨The cost of catv cable is less.
➨The outer conductor in catv cable is used to improve attenuation and shield effectiveness. This can be further enhanced with the use of second foil or braid known as jacket (C2 as designated in the figure-1). The jacket is used as protective cover from the environment and makes overall catv cable as flame retardant.
➨It is less susceptible to noise or interference (EMI or RFI) compare to twisted pair cable.
➨It supports high bandwidth signal transmission compare to twisted pair.
➨It is easy to wire and easy to expand due to flexibility.
➨It allows high transfer rates with catv cable having better shielding materials.
