Coaxial Cable
Coaxial cable is a rounded cable with a center conductor and a braided or solid metallic shield, usually copper or aluminum. The center conductor is separated from the outer shield by a dielectric, which is usually foam, air or a compressed gas such as nitrogen. The shield is covered with an outer cable sheath.
Coaxial cable is considered an unbalanced line.
