A coaxial cable includes a core, an insulating layer, a shielding layer, a
sheathing layer. The core includes an amount of carbon nanotubes having
at least one conductive coating disposed about the carbon nanotubes. The
carbon nanotubes are orderly arranged. The insulating layer is about the
core. The shielding layer is about the insulating layer. The sheathing
layer is about the shielding layer.
