Coaxial Cable & Accessories
Coaxial Cables (coax) have an inner conductor surrounded by an insulating layer, surrounded by a conducting shield. Coaxial cables also frequently have an insulating outer jacket. Coaxial cables are used to carry high frequency electrical signals with low signal loss. Here is more information on Coaxial Cables.
