What is Cable TV Coax?

Everyone, or just about everyone, has heard of coax cable. Most people know that it is cable that is used in conjunction with cable television. But do you know what coax cable is exactly?

Coax cable is a type of copper cable that cable television companies use to connect a community antenna from their satellite to the person's home who has purchased the cable or to a place of business.

Coax cable was first developed in 1929 but wasn't actually used by a business until 1941 when AT&T used it for a cross-continental transmission.
