Ratna CO-X

Co-Axial Cables for CATV Networks

- High quality Co-axial for Cable TV network
- Notch free attenuation values over wide range of frequencies
- The special jacketing offers increased life even in rugged conditions

Conductor : The central conductor is made of solid electrolytic grade copper conductor, which has distinct advantages over traditional copper conductor.

Insulation : The insulation provided over the conductor is of foam PE which acts as a dielectric.

Screen : Aluminium Mylar tape is provided over the insulated conductor to shield the conductor and ensure disturbance free transmission of signals.

Braiding : The braiding is generally provided with 60% coverage of ATC (Annealed tinned copper) / AL (alloy).

Marking : The cables are marked "RATNA CO-X".
