i can guarantee you that your wildwood does not have a satellite on top.
do you have a crankup tv antenna? there's no switch or lever, just a crank on the trailer's ceiling.
have you got up on the roof to look?
some of the entry level trailers, like the wildwood x-lite, have tv hookups as an option, not standard.
if it does, the outside cable plug is usually under a covered hinged lid.
this should have been covered during the PDI from the dealership.
