RG6/U Dual shield is used for security systems, for analogue TV antenna cabling and for CCTV. It features a copper clad steel inner conductor. Tri-shield and quad-shield versions of RG6/U provide additional EMI shielding for digital applications.

RG11/U Quad-Shield is used for the same applications as RG6/U for either backbone cabling or for long distribution runs. It features a copper clad steel inner conductor.

RG59U is available with either solid copper or copper clad steel centre conductor. It is suitable for basic analogue TV antenna feeds in residential applications and for basic CCTV systems over short cable runs. The copper clad steel type has high tensile strength and should be used when terminating the cable with F type connectors.

RGB Component Connector: A high-end way of sending computer signals to monitors and displays via five separate component signals: red, green, blue, horizontal (grey cable) and vertical (black cable). Physically, the connectors can be phono or BNC types.
