Coaxial cable wire is used for cable TV connections in your home. Each end of the wire has a long needle in the center that fits into the input and output ports of your TV and cable source. If you have multiple coaxial wires that don’t quite reach from the cable source in your home to your TV or receiver box, you can splice multiple wires together, connecting multiple wires to create a single wire. This requires some specialized equipment, but is often cheaper than purchasing an extended-length coaxial cable. Writer Bio
