Information about Rg 6
RG-6/U is a common type of coaxial cable used in a wide variety of residential and commercial applications. The term "RG-6" itself is quite generic and refers to a wide variety of cable designs, which differ from one another in shielding characteristics, center conductor composition, and dielectric type. RG-6 was originally a military spec where RG means Radio Guide, but is now obsolete; in practice, the term "RG-6" is generally used to refer to coaxial cables with an 18 AWG center conductor and 75 ohm characteristic impedance.
The most commonly-recognized variety of RG-6 is CATV distribution coax, used to route cable television signals to and within homes, and RG-6 type cables have become the standard for CATV, mostly replacing the smaller RG-59, in recent years. CATV distribution coax typically has a copper-coated steel center conductor and a combination aluminum foil/aluminum braid shield, typically with low coverage (about 60%). RG-6 type cables are also used in professional video applications, carrying either baseband analog video signals or serial digital interface (SDI) signals; in these applications, the center conductor is ordinarily solid copper, the shielding is much heavier (typically aluminum foil/95% copper braid), and tolerances are more tightly controlled, to improve impedance stability.
RG-6 cables typically are fitted with some type of connector at each end; in CATV distribution applications, these are typically F connector style; in professional baseband video, BNC connectors; and in consumer a/v applications other than RF and CATV, RCA plugs.
