What is coaxial cable?

 Carrying signals from one device to another for decades, and coaxial cable was created in the 1930s to transport radio frequency signals, which are the ones that go from an antenna to receivers. Cables that have two conductors on the same axis are called coaxial.

These two conductors are, on the one hand, an outer cylinder that is a braided metal mesh (B) that serves as a return conductor and shielding of the interior, stabilizing its electrical parameters. In the center of the cable there is a copper core (D) which is the second conductor, the most important, and it is the one that carries the information. Between the two there is a thick insulating layer (C) that separates them, and on the outside another insulating layer (A) like that of other cables.
