Coax Cable FAQs

Coaxial cables are conductor cables designed to transmit data to electronic devices. They are used to carry radio, television, satellite and internet cable information between devices and satellites, antenna and cable services.

Q: How is coaxial different from other wires?

A: Coaxial is different from other wires, such as electrical line and stereo wires, because it is insulated. This prevents outside sources from interfering with the transmission of signals. For example, if coaxial was not well insulated, the television would go blurry every time a cell phone rang or lightening struck.

Q: Coaxial is identified by RG and then a number; what does that classification mean?

A: RG is an old acronym for the military classification of cables and stands for Radio grade. The number refers to how heavy the wire is. The lower the number the higher the cable grade and the more efficient the cable is as a conductor of signals.

Q: What are the most common coaxial cable types?

A: RG-6 and RG-60 are two of the most common cable types used residentially. RG-60 is used to carry normal TV antenna signals and standard cable connections; it has one layer of insulation and a thin conductive core. RG-6 is used to carry high definition signals and high speed internet connections. It has up to four layers of insulation and a much thicker core than lower grade coaxial cables.

Q: What is the difference between indoor and outdoor coaxial cables?

A: Indoor coaxial cables offer no waterproof guarantee and have a thinner braiding screen and exterior protective coating. Always use outdoor coaxial when available. They are more resistant to spills, dampness, crushing and cutting.
