Why Use Coaxial Cable?
Coaxial cable has many advantages over twisted-pair cable but also a few disadvantages. It has a large frequency range which allows it to carry multiple signals, making it ideal for carrying many cable television broadcasts. Each channel also has greater bandwidth that allows for high definition video. The shielding reduces crosstalk and other interference, allowing for greater cable lengths between amplifiers. However, coaxial cable is more expensive to install, and it uses a network topology that is prone to congestion.
