Tip Improving COAX cable connectivity in your RV or Motorhome

Interesting. So the fix was the swap of splitters from 5-1000Mhz to 5-2000Mhz and not just terminating the open ports on the existing splitter? I may have to look at that on the home setup and replace those old splitters.

@Buster ... not sure which item is the main issue but I did both and mine went from "bad to good". If you go through the trouble of getting under that sink I would sure do both.

I think @TJ&LadyDi hit the nail on the head. Terminators are always a good idea as a splitter is also a combiner. Unused ports on a splitter in theory can take in stray signals and cause picture degredation but is practice this is usually not the main problem.

Unless things have changed recently, the mainstream cable companies transmit signals in the 50-1000Mhz range these days. The 50-550MHz range was the standard 20+ years ago prior to the explostion of channel options. The 5-50Mhz range is used for the return path back to the cable companies (i.e. send info back on Pay Per View purchases). Cable TV in an RV park should operate similarly although they could in theory be their own cable company and transmit differently - i.e to @Neal 's point above.

Either way, the new splitters and possibly terminators solved the problem for multiple people which is the goal.

P.S. If you ever want to see how cheap a splitter is made, just open one up and you'll wonder how you even get a signal in the first place.
