What is the maximum lenght for coaxial cable?
Depends on the data rate.The higher the bandwith, the shorter the lenght will be. For example
analog standard definition television will run 1000Ft on a good quality, but HD video is limited
RG59 Coax with Bare Copper versus Coax with Copper Cover Aluminium
Utilizing an RG-59 CCTV coaxial cable with a copper covered aluminum braid does not result
in compromised electrical performance when compared to an RG-59 CCTV cable with a bare copper
braided shield. Insertion Loss, Return Loss and Characteristic Impedance performance all meet the
industry standard requirements.
The only difference between the copper clad aluminum braided product and the bare copper braided product is
the shield DC Resistance. As a result, the recommended typical run length for the CCA shielded cable is
up to 600 ft. versus 750 ft. for a copper RG-59 coax.
