A bonded aluminum foil and 60% aluminum braid over another foil and 40% alumninum braid provide 100% shield coverage. Use for CL1, CL2, CM, CMX and CMG installations. Swept tested to 3 GHz to ensure performance at applicable frequencies. To help you keep track of cable used, the cable jacket is sequentially marked every two feet.
