You should have an exterior cable connector that connects to campground cable. For the outside cable to work the antenna booster has to be off. The Seiki TVs won’t work on some campgrounds without a converter box, the Seiki does not have a QAM converter which is needed for most cable tv, this is why you need a converter.
I changed out my TVs to Samsung’s with digital tuners, I get twice as many over the air channels and now don’t need a converter box.
