Coax cable routing

[Oldlaxer1]

So Comcast was out to troubleshoot our lousy connection and naturally they blamed the wiring inside the boat. Does anyone know the routing of the coax from the port inlet at the electrical connection panel to the Stb engine room? I've got to pull new cable and was hoping to get some insight. Thanks in advance.

Every splitter along the way reduces the signal strength. #1, get a roll of coax and run it directly from the dock to the largest screen TV you have and compare. If that makes a big improvement, #2 buy one (or more) of those signal amplifiers and see if that doesn't improve you current configuration. Coax connections go bad like any other connection exposed to the elements. When I replace a connection, I use waterproof connectors AND heat shrink over that. The connections are usually in tight spots, so I want to do the job one time only.

I have the same issues on my dock. Comcast provides service to the marina and the marina extends it to the docks. Land-side transformers are always going down. So a signal booster is a must for me.

Thanks. I fought the idea that it was internal to the boat until I ran directly from the pedestal (brand new cable) to the modem. I'd been seeing internet speed tests in the teens and after connecting directly they were above 200mbs. I only have two tv's and of course the modem. I have a powered amplifier in the stb engine room. Tv signals have been ok. Internet speed is where the connection really suffered. I'll start poking around to see where the cable leads. Intuitively I wouldn't think the cable itself wouldn't go bad, just the connections. Is that faulty thinking?

Yes and no. Just like electrical wire, you may have to cut it back to get to clean conductors. Then look for sharp bends and kinks or creases.

I redid mine, orig set up was from a HD antenna going to the port aft cabinet then to all 4tvs. I removed the panel on the stbd side where catv port is outside and what was there was cut, old and deteriated. I ran mine down to eng room then up to stbd cabinet where the air handler is and mounted a connection point there. It's then split to TV and modem there. You just might need to crimp new ends on what you have and replace the stud aka barrel.
