We just purchased a 2022 Dutchman Kodiak 2921fkds and I noticed that there is only one Ant Jack for the main TV. Yet, on the outside there are two incoming jacks, one for cable & one for satellite. I am assuming that they all tie together somewhere. Does that mean I will need to use a splitter at the TV so one coax goes to Tv for local reception and the other to the Satellite receiver? This is is the first time I have seen this, most have two jacks at TV.
