RG6 – Flexible Coaxial Cable (75 Ohm)

About

• RG-6 is a popular type of coaxial cable used in a wide variety of residential and commercial applications. An RG6 coaxial cable has a characteristic impedance of 75 ohms. The RG-6 is primarily used for cable and satellite signal transmission for residential or commercial installations.
• RG was originally a unit indicator for bulk radio frequency (RF) cable in the U.S. military’s Joint Electronics Type Designation System.
• RG-6 is generally used to refer to coaxial cables with an 18 AWG (1.024 mm) center conductor and 75 ohm characteristic impedance.
• RG-6 cables have larger conductors, so they provide better signal quality. They have thicker dielectric insulation and are made with a different kind of shielding, allowing them to handle GHz level signals more effectively.

Usage:

• This coaxial cable is very easy to bend for wall or ceiling installations and preferred choice to relay cable television signals and commercial entertainment systems.
• Satellite and internet signals run at higher frequencies than traditional analog video, and when TV broadcasts changed from analog to digital, and cable companies started switching to digital, the higher frequencies made it necessary to find a more effective coaxial cable. RG6 cable was designed to cover these needs.
• Coaxial cables can be used to carry signals for internet connections, but internet signals run at higher frequencies than traditional analog video.

Special types of RG6 Cables:

• RG6 Quad Shielded cables (RG6Q) and RG6 Dual Shielded cables (RG6) are both coaxial cables.
• RG6Q and RG6 cables are not interchangeable. Physical and performance differences between the two cables are to be considered when deciding which cable you will need.
• Both RG6 and RG6Q cables have the same size conductor (18 AWG Copper-Clad Steel), an aluminum braid layer, and a foil layer.
• The main difference between the two cables lies in the amount of shielding.
• An RG6 cable has only two layers of shielding.

RG6 cable Spec:

• 60% Aluminum Braid
• Aluminum foil polyester tape
• Nitrogen-Injected Foam Polyethylene Dielectric insulation
• 18 AWG Copper-Clad Steel Conductor
• An RG6Q cable has four total layers of shielding.

RG6Q cable Spec:

• 100% coverage APA foil/40% Aluminum Alloyed Braid
• Aluminum Foil-Polyester Tape
• Nitrogen-Injected Foam Polyethylene Dielectric insulation
• 18 AWG Copper-Clad Steel Conductor
• The additional layers of shielding will also make the RG6Q cable slightly thicker, and therefore heavier, than the RG6 cable. The cable diameter of the RG6Q cable is also slightly larger than the RG6 cable.
