I come from a plant that was just upgraded about 5 years ago. So its still in pretty good shape. So most of our ingress is issues from the tap to the home from the rg6 cable. Clean up your ingress in your homes when doing Installs and Service calls and your snr will get better. This will keep your noise floor down and the entire system will run better.
