Melbourne TV Cable question

[Imazman]

Our 2018 Melbourne 24K has a cable inlet at the water control panel and a cable outlet in cabinet above the door. This one above the door goes to the TV and has an ampliier which I use to watch over the air broadcasts just fine. Now questions...there are two more outlets in the cabinet...what are these for? And where are the other ends of these? I have a mobile Dish antenna and Wally receiver and tried to connect the antenna up to the water panel and then the Wally receiver to the single outlet and turned off amplifier but it didn't work for the Dish.

Thanks for everyone's help...so much to figure out!

The others are for a roof satellite connection. The other ends are buried under the roof. I have a diagram where they are under the roof for a 2016 if you would like to see that. I am not sure if it would be the same for a 2018. Have you tried bypassing the amplifier for your portable dish? Even when it is off there may be something that interferes with the signal.
