"Achieving the best picture possible for your composite video installations requires the best cable. Copper clad steel conductors are fine for RF applications like antennas, cable television and satellite installations, but may result in poor quality composite video signals. This Impact Acoustics coax cable is designed specifically for installations where you intend to run composite video, RGBHV video, component video and even surveillance systems! This cable has 18AWG bare copper center conductor surrounded by a foam polyethylene dielectric, 95% copper braid and PVC jacket. Use for CL1, CL2, CM, CMX and CMG installations. Sweep-tested to 3GHz to ensure performance. To help you keep track of cable used, the cable jacket is sequentially marked every two feet. Features: 18AWG solid bare copper center conductor. 95% bare copper shield. Foam polyethylene dielectric. CM/CL2 rated PVC jacket. Sweep tested to 3GHz. Sequential foot marking ends at 0 feet."
