Flexible Cable for Antennae/Leaky Coaxial Cable

1. General informattion

Inner conductor strictly adopt international standard E-circular copper wire . Insulation is HP FPE, which is low-attenuation, moisture proof, etc.

High density braid and Al belt cigarette wrap, especially for long-distance transmission. With squra sheilding net and argon arc welding Al tube brank, much more suitable for HFC wideband network demand.

Jacket is high anti-fire, anti-cold, moisture proof, guarantee long service-life of coaxial cable.
