If I recall correctly, the outside coax cable connector feeds the inside coax cable connector when the antenna amp button is in the off position (out). When the antenna button is pushed in, the signal is fed from the rooftop antenna via the amp for TV and the outside cable connector is disconnected except maybe to a bedroom connector. I've never been at a campsite where the cable connection from the campground also contained Internet. Internet was available via wifi only. Your setup may be different but this will give you a few things to check out with the campground host.
