A coaxial cable connects cable television service into a home-viewing device such as a television, cable box, VCR or DVD player. The wires are usually made of copper to provide input directly from a cable company's community feed. Coaxial cables contain the signal wire surrounded by an insulation sheath with another grounding wire surrounding the sheath. The entire cable is encased in one large sheath. Cleaning the connection of dust and grime prior to installing the cable provides a stable connection with continuous feed.
Disconnect both ends of the coaxial cable.
