They are used for carrying television networks from a distributor to individual houses which is why the service is known as cable tv.
What does a coaxial cable do.
It has been around for a long time as a technology since the early 20th century and has many singular advantages for reliable accurate transmission.
It is used in such applications as telephone trunklines broadband internet networking cables high speed computer data busses cable television signals and connecting radio transmitters and receivers to their antennas.
Coaxial cable is a type of copper cable specially built with a metal shield and other components engineered to block signal interference.
Coaxial cable is a type of transmission line used to carry high frequency electrical signals with low losses.
It is primarily used by cable tv companies to connect their satellite antenna facilities to customer homes and businesses.
The insulators also protect the signal from outside magnetic fields.
Their distinct thick round shape is due to a heavy layer of interior insulation which is designed in part to reduce the effect of magnetic fields on the signal the cable carries as well as reduce the amount of signal loss which occurs as signals pass through.
The core similar to a copper ethernet cable is a single copper wire.
The insulator is there for protection and connection as it s dielectric.
The shield is usually made of copper as well reducing or eliminating any electromagnetic interference.
A coaxial cable has four main parts.
A coaxial cable sometimes called a coax is a special format of electrical cable.
A coaxial cable carries a signal which goes across the center copper wire as well as the metal shield.
Coaxial cables are essentially just cables made of wire which carry radio or television signals.
It has also been used extensively within homes.
The insulators keep the signals from coming in contact with or cancelling out each other.
Both of these metal conductors generate a magnetic field.
Coaxial cable is commonly used by cable operators telephone companies and internet providers around the world to convey data video and voice communications to customers.
