RG coaxial (high-frequency coax)



Wide range of coax cables designed to carry high-frequency or broadband signals. Most commonly single core but twin, multicore and composite versions (with power cores) are available in some types.

Product Specification

RG coaxial (coax) cable is designed to carry high-frequency or broadband signals. Twin core, multicore and composite versions (with power cores) are available in some types.

Coax cable is called “coaxial” because it includes one physical channel (inner conductor) that carries the signal surrounded by another concentric physical channel (braid screen), both running along the same axis. The two channels are separated by a precisely measured tubular insulating layer (dielectric) to achieve constant conductor spacing.

Black PVC sheathed RG coaxial cables are suitable for internal or external use whereas the white PVC version is for internal use only. PE sheathing is for ducted applications, FEP sheathing is for high temperature use and LSZH sheathed cables provide increased safety in the case of fire.

Note: low smoke zero halogen / halogen free (LSZH, LSOH, LSHF, OHLS) should not be confused with LSF (low smoke and fume), an in-depth explanation is shown on our LSZH Control Flex front page.
