Coaxial and TwinAxial Cable

Coaxial cable is used to carry RF, video, broadcast, data, antenna, MATV, CATV, CCTV, and other communication signals. It is commonly used where the cable needs to support signal transmission while helping protect against interference and signal loss.

The right coaxial cable depends on the application, RG type, impedance, shielding, jacket rating, conductor material, cable length, and equipment requirements.

Twinaxial cable, also called twinax cable, is used for signal transmission where two conductors are carried within a shielded cable construction. It may be used in data, control, instrumentation, computer, and specialty communication applications where balanced signal performance or paired conductor construction is required.

The correct twinaxial cable depends on conductor size, insulation, shielding, jacket material, impedance, capacitance, voltage rating, and the equipment or system specification.

Coaxial cable typically has one central conductor surrounded by insulation, shielding, and an outer jacket. Twinaxial cable has two conductors within a shielded construction.

Coaxial cable is commonly used for RF, video, broadcast, antenna, CATV, MATV, and CCTV applications. Twinaxial cable is commonly used where the system requires a shielded two-conductor signal path. The right choice depends on the equipment, signal type, impedance, cable length, and project specification.

RG numbers identify different coaxial cable constructions, such as RG 6, RG 8, RG 11, RG 58, RG 59, and RG 62. Each RG type may have different conductor size, impedance, outside diameter, shielding, capacitance, attenuation, jacket, and application characteristics.

Buyers should not choose cable by RG number alone. The cable should also match the signal type, equipment requirement, installation environment, and project specification.

To choose the right cable, start with the signal and equipment requirements. Confirm whether the application is RF, video, broadcast, MATV, CATV, LAN, CCTV, antenna, data, control, or specialty communication. Then compare RG type, impedance, conductor material, shielding, jacket rating, plenum requirement, outside diameter, capacitance, velocity of propagation, attenuation, voltage rating, and required length.

For quote requests, provide the RG type or cable type, required footage, impedance, shield requirement, jacket requirement, application, and any equipment or project specifications.
