A Coaxial cable is a type of electrical cable designed to carry high-frequency signals with low loss. It consists of a central metal conductor surrounded by an insulating layer, a woven metal shield that blocks external interference and an outer protective jacket.
This construction ensures that signals such as television broadcasts, broadband internet data and radio communications travel along the central conductor without picking up noise from nearby electrical sources. Common in homes and businesses, coaxial cables connect aerials and satellite dishes to receivers and link cable modems to internet service providers.
