TV Coax wiring

[TammyandTony]

I count 5 coax outlets
- side of fridge
- front of sink
- floor by bedroom
- outside front side
- outside back side

Does anyone know how these are connected ?
The wiring diagrams I have do not show the coax wiring.

Is 1 the input and the other 4 tied to a splitter ?
- any idea where the splitter or wiring is ?

I have no roof antenna and am trying to understand how to connect antenna and TV(s).

Thanks for any help,
