BH 3850 Sat Hookups

In the docking center there are two Sat hookups for both the rear of the coach and two for the bedroom. Atleast that is how they are labeled. Question is why two connections each? How are they wired? It doesnt match up to the wiring diagram posted on the factory web site.

Thank you in advance for the info. and help.

one of each is the feed that is dropped down from the satellite prep on the roof, the other is the feed to the ent center and bedroom.

Thank you!
