Going with RG6 Long-Run Cables - dummies

By Danny Briere, Pat Hurley

You can use RG6 coaxial long-runs to connect your home theater to the rest of your home, perhaps to share a video source device with TVs in other rooms. RG6 cables are designed to minimize signal loss and get your audio and video to any spot in the house.

Here are some details you should know about RG6 long-run cables:

  • RG6 is a coaxial cable that carries video signals (and the associated audio tracks) from antennas, satellite dishes, and cable TV feeds from the street.

  • With devices called modulators, you can actually create in-house TV channels and use RG6 cables to share your own video sources with other TVs in the house.

  • The connectors on an RG6 cable are known as F connectors.

Coaxial cable (usually just called coax) is a metallic cable most often used for transmitting radio frequency (RF) signals, such as broadband television video and radio signals. Coaxial cable contains two conductors, or axes, to carry data. A layer of dielectric insulating material surrounds a single center conductor. The other conductor is a metal shield, usually made of a braided metallic wiring, that goes around the dielectric (insulating) layer. The outermost layer of coax cable is an insulating jacket.

You may encounter coaxial cables labeled RG6QS or RG6 Quad Shield, which means that the cable has additional shielding beneath the cable jacket — four layers, as the quad implies. These layers provide additional protection against interference from external sources. Quad Shield coax doesn’t cost a lot more than RG6 coax, and it’s worth the investment.
