what does coax cable look like

Coaxial cable is a type of electrical cable that is commonly used for transmitting radio frequency signals. It consists of a central conductor, which is surrounded by a dielectric insulating layer, a metallic shield, and an outer insulating layer. The outer insulating layer is typically made of PVC or other materials to protect the cable from environmental factors. Coaxial cable is used in a variety of applications, including cable television, internet connections, and telecommunications. It is known for its durability, high bandwidth capacity, and resistance to electromagnetic interference, making it a popular choice for transmitting signals over long distances. Overall, coaxial cable is an essential component in modern communication systems, providing reliable and efficient signal transmission for a wide range of applications.
