Dan,
That is what I was planning on doing, I just can't find the coax connector for the antennea because the reciever I have is an older model with the coax out that I wanted to mirror on all of the TV's because on the aerial antennea does send a signal to all of the tv's so there has to be a 1-4 way splitter somewhere on the rig, for all of the tv's to recieve a signal.
Our 2011 LM doesn't have the outside TV. We have living room, bedroom, and basement coax connectors. The signal from antenna joins the cable at the signal booster in the bedroom. The combined output goes to the basement where there's a 2 way splitter. One side goes to the basement connector and the other side continues to the living room connector.
You may have a similar arrangement with another 2 way splitter somewhere that handles the outside TV and living room. I doubt there's a 3-way or 4-way splitter.
I think some people have just taken over their living room coax connectors to run satellite receiver output to the other TVs. But then you don't get to use cable or antenna on that TV.
Another choice might be to locate the satellite receiver in the bedroom and use a diplexer to combine it with the line coming out of the signal booster (assuming that's where your signal booster is located).
Something else you could try is to call Heartland Customer Service at 877-262-8032 / 574-262-8030. Have your VIN # ready. Ask them to email a copy of the coax layout for your Gateway. That'll show you approximately where the splitters are located. If you get a copy, please forward it to
