Sir, can you please tell me what is the maximum permissible working distance of RG11 cable in meters for CATV?
RG-11 attenuates at 9 dB per 1000' @ 1 GHz (which is the approximate bandwidth you'd need for CATV).
So, then the question becomes, how much gain is in each trunk amplifier? If it's 9 dB, then you can run 1000'.
In order to fully answer the question, I would need to know what the gain of the trunk amplifiers is, and what the actual bandwidth of the system is.
