Antenna Issue

[rames14]

I have an antenna question on the wiring. I am not getting as many channels on my living room tv as on the bedroom tv. I ran a long cable from the booster to the tv and got all of the channels as the bedroom. So, I know the antenna, booster and tv are all working properly. So, there is a bad connection between the booster and the living room. I also have the same issue on the outside tv. I have checked the connections coming into the slide and they are solid. I am wondering if there is a splitter somewhere that splits the signal from the booster to the outside and living room tv’s. If so, where is it located? I have a 2015 3160, so it is probably wired similar to other models in the same year. Hoping I don’t need to drop the belly, but it may lead there. Thanks in advance.
