Are there analog channels on the cable that you don't like?...If so switch your modulators to use those and get the correct filters to remove those channels ahead of the injection point.

Nowadays if you have mixed signal cable anything not used for analog is likely being used for digital, and not just cable TV, internet, phone, on-demand, and other things get crammed down the pipe. If you receive any other services you could be jamming those too.

Be careful your not letting any of your local signal back feed down the line, or you could be interfering with other's service, and the cable co will come down on you hard if you do that (they will also, if randomly asked, discourage your system for fear it will interfere).

These days cable co's have filled their bandwidth to be competitive so finding a 'dead spot' to transmit is not necessarily practical.
