100% coax is super susceptible to cuts and exposure to weather. You’re probably degrading the whole node with that. even a little bit of loss of shield can compromise the low band return spectrum and the whole nodes upstream. this is why cable modem is the new DSL. it sucks for performance and reliability. Any one customer without even trying can cause an outage on coax. Lets unplug that TV with cable card and a center pin thats too long … boom antenna. coax not tightened down enough on a splitter, modem or set top box. If your not using a PPC SignalTight or SignalTight Clone it will ingress low band. At some point you almost have to look at a coax like its a water pipe. We had a video headend that had leaks like this … was so bad we either have to replace all cable or just put in filters. the filters worked better than expected and lowered the noise floor 5-8 db more than before the ingress problem even existed.
i have my hands in some coax hub and headend work but mostly hard troubleshooting like odd leaks/ingress problems that stuff like this picture cause.
there was a video by Brady Volp a well known expert in the docsis/coax space about how even cable staples will cause signal reflections. its a hard space to keep functional and the more stringent the requirements get the harder it is.
