Application |
Standards |
|
Coaxial CATV cable, applied as trunk line between main station and house connections. Suitable for direct laying in ground or for fixed installation in cable tubes and canals. Foamed polyethylene of low dielectric constant enables low attenuation, low signal distortion and exceptionally high-speed signal diffusion. Polyethylene sheath provides resistance against external impacts. |
