What Does A Coaxial Cable Look Like?

Coaxial cable has a distinct thick, round shape because of its interior insulation layer. Its size makes it look very different to other types of cable, such as twisted pair or Ethernet cable. The most commons sizes of coaxial cable are RG-6, RG-11 and RG-59 – some of the size differences are demonstrated in the image below.

Coaxial cables are available in a variety of colours including black, brown and white.
