Martin,
There are two Satellite connections in the Docking Station.. one is for the tv... the other is for the chance that you want to install a Roof Mounted Satellite System.
The one that is for your TV... in our BigHorn... runs to the TV in the Living room.
The Other one is a cable that is coiled inside the roof... so when a dealer would not need to run a cable through the RV when he was installing one of those automatic roof top Dish system.
