My 2016 Hurricane (Windsport twin) did not have a separate satellite hookup. If you try to use the cable connection above the wet bay, it won't work because of the splitters used to route signal to all TVs. The sat receiver needs a direct uninterrupted connection from the dome.
You can always add a separate connection and route the cables to your sat receiver. Most domes support 2 receivers, so you would need 2 additional connections if using 2 different receivers. There are kits to add the cable feeds on the outside of your RV. Here is a kit on Amazon that has both the external connection and the internal wall plate (plus some coax cable.)
