Low-loss, quad-shielded, 75 Ohm coax for head end, drop cable applications. As with most other Gepco coax products, head end cable utilizes a gas-injected dielectric that reduces high frequency attenuation and increases the velocity of propagation. Unique to head end cable is a silver-plated, copper-clad steel conductor which reduces the resistance at the surface area of the conductor, further lowering the high frequency attenuation of the cable. To provide exceptional protection from stray RF and EMI, a dense quad shield with dual 95% aluminum braids is utilized.
