I had a roof leak over the winter. I found two spots where water came in. I took off the old caulk and recaulked it. I have not had any water in the camper since. However, this has been happening ...
Those antenna can have an area between where it cranks up and holding bracket on the roof where water can leak. There is a rubber condom looking thing that covers where the wire enters the rv and that area cash be problem with leaks. Some sealant under that rubber piece solves that if that is where it's coming from.
