RG6

RG-6 is a designation for a family of coaxial cables commonly used for high-frequency signal transmission. It is a 75-ohm coax, widely employed in cable television, satellite television, and broadband internet installations. Compared with RG-59, RG-6 generally offers lower signal loss and better shielding, making it suitable for longer runs and higher frequency applications.

Construction typically includes a copper center conductor, a dielectric insulator, a shield made of foil and braided material, and an outer jacket of PVC or polyethylene. Variants exist, such as RG-6/U and quad-shield RG-6/UQ, with additional shielding layers to further minimize interference and crosstalk.

Impedance and performance: The nominal impedance is 75 ohms. RG-6 cables are designed to carry signals from a few megahertz up to several gigahertz, supporting television, satellite feeds, and other high-frequency services.

Applications: The cable is widely used to distribute cable TV signals, connect satellite dish systems to receivers, and provide broadband internet in residential and commercial settings. Connectors commonly paired with RG-6 in consumer installations include F-type connectors, while professional installations may use BNC or other connector types.

Standards and designation: The RG naming convention originates from mid-20th-century military designations and does not represent a strict universal standard. As a result, exact constructions can vary by manufacturer. When selecting RG-6, consider frequency rating, shielding, and jacket material to suit the intended environment.

Installation notes: For outdoor or long runs, ensure proper sealing and moisture protection, use appropriate connectors, and avoid sharp bends to maintain signal integrity and minimize loss.
