What is a coaxial cable and how does it work?
A coaxial cable, often referred to as coax cable, is a type of electrical cable that consists of a central conductor, an insulating layer, a metallic shield, and an outer insulating layer. The central conductor is typically made of copper or aluminum and is responsible for transmitting signals. The insulating layer provides separation between the central conductor and the metallic shield, which helps to protect against interference and improves signal quality. The metallic shield also serves as a ground and helps to prevent external electromagnetic interference, making coaxial cables reliable for various applications, including TV and internet connections.
Coaxial cables work by carrying radio frequency (RF) signals over their copper core. These signals can come from different sources, such as cable television providers or satellite dishes. The construction of the coaxial cable allows for efficient signal transmission over long distances without significant loss in quality. This is why coaxial cables are commonly used for cable TV connections, as they deliver high-frequency signals effectively to provide clear audio and video quality.
