Coaxial Cables
PRINT DOCUMENT
For radio, video, audio and base-band telecom applications
  • 75 Ohm Characteristic impedance cables, ideally suited for, owing to lower losses:

    • - Video transmission to end equipments
    - Audio transmission to end equipments
    - Base-band telecom transmission

  • Manufactured out of imported grades of polyethylene – especially suited for the coaxial cables.
  • Available in standard lengths of 100 Mtr coils. Can also be supplied in running lengths wound on wooden / steel drums.
    •
