Center conductor——The copper wire or the steel-copper conductor is what transmits a signal to your TV. If you want a stiff cable that will not break, then go with one that has stiffer wires so they are less likely to bend which would result in lost signals along its length making them weaker over time.
Dielectric insulator——The whole point of this design is to let the signal flow through but not any other electricity. The inside wire has a dielectric insulator surrounding it and then an outer conductor, which shields the inner one from interference by electrical currents that move in adjacent surfaces around it.
Outer conductor——You’ve likely seen the yellow, black, and white RG6 coaxial cable in a home’s television setup. The outer conductor of this type of cable is also known as the “foil shields” or “braided shield.” It is the durable, protective, and conductive shield of a coaxial cable that provides shielding from electromagnetic interference on coaxial cable lines.
Outer layer——The final layer on a coaxial cable is a PVC jacket that protects the electrical cable from water and dirt, allowing coaxial cable suitable for outdoor or indoor use. Outdoor applications may require protection against UV light oxidation or rodent damage while some versions are designed to resist direct burial. However, some internal applications may omit the insulation jacket.
Connectors——Coaxial cable connectors are used to connect cables to other devices and maintain the cable’s shielding. F-type connectors are the most common. They’re used with RG6 coaxial cable and RG11 to make a cable connection for cable televisions, cable modems, VCRs, satellite receivers, cable boxes, digital routers, TV antenna cable, or other devices with F-type coaxial port. F-type connectors come in two types: twist-on and crimp. Twist-on connectors don’t create as high a quality of connection as the crimp style.
