Transmission Characteristic:
Because the high-frequency signal have the skin effect characteristics on conductor transmission, cable television signals transfer in the surface of the copper which thickness is more than 0.008mm. CCA inner conductor can fully meet the requirements of signal transmission, the signal transmission characteristics is consistent with the same diameter copper.
