Product Specification

CT coaxial (coax) cable is designed to transmit satellite, CCTV, television and video signals. The term CT was a originally a manufacturers brand name for satellite coaxial cable, that company is no longer in business but many people continue to use the reference. Alternative references include ST, DT, TV, MF, WF and many more. 

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 sheathed cables are suitable for internal or external use, white sheathed cables are suitable for internal use only. Duct Grade (thick PE) sheathed cables are suitable for use in ducts 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.
