Why do you think you have a bad C/N ratio? I believe the FCC mandate is 43dB at the set top or tv or CPE.
Remember NOISE. You have to keep the noise out and the noise floor low. 60dB at the headend.
Devide and conquer. Follow the line. When you see a significant drop between noise and carrier start doing the basics. Ingress,thermal noise, mechanical noise, lose set screws, looses connectors, water,broken cable, no termination, back feed from houses.
Alot of times where you have ingress you have egress. Use your leak detector. Go from the poor picture and work back until you find acceptable c/n and divide and conquer.
Good luck.
