Bad TV Reception

[Jim]

Recently the only TV that gets good reception is the one above the dash. The other 3 have different degrees of reception with the one in the bedroom being almost unusable. Well, the higher channels are reasonable, but the lower you go the worse it gets.

Anyone know why? It wasn't always like this. Just started a few months ago.

Sounds like you may have a failing splitter, @Jim.

Only one TV works well so would that mean 3 splitters are failing?

Tip - Improving COAX cable connectivity in your RV or Motorhome

I was at a campground earlier this year and had issues with the cable TV as they are all digital cable. I struggled in my 2017 Newmar Ventana to get a good picture on all TV's and there number of channels being detected in the channel search was inconsistent. It was time to investigate. There...

Not necessarily. If the main cable feed is split to the front TV and another splitter for the other TVs, just the second splitter could be bad...or, the third. Splitters usually come in two-port and four-port versions (1 in-2 out or 1 in-4 out). It is common for RV installations to have daisy-chained splitters to feed several locations. If one splitter in the daisy-chain goes bad, there will be signal loss in the ones following it.

These are the replacement splitters I have have used.

It is also common for unused ports to not be terminated properly...and, they should be. Unterminated ports can also cause signal loss, though I wouldn't expect that situation to suddenly appear. Here are the proper port terminations I have used.

Finally, you may have a piece of coax going bad somewhere between the front TV and the other TVs. Have you done any work in an area where you might have pinched, cut or pierced with a nail/screw a piece of coax?

Good luck.

Looks like @Neal and I doubled up on you, but I don't think our replies conflict. He is spot on.
