Cable Cos in State College PA per
HERE..
Comcast Xfinity..
From what I can tell, unless you have one or two specific brands of TV you WILL need a set top box (AKA Cable Converter)..
From
HERE it is claimed that only Samsung (the first set) and later 2018 LG sets will be compatible with Comcast cable directly without a set top box.
Cable Cos have pretty much pulled the plug on analog channels and even have set the QAM data bit to "private", they are no longer compelled to provide open in the clear cable signals PROVIDED they offer FREE basic set top boxes..
OP should be able to contact the local cable Co office to get full details on a free set top box to use..
I suspect the campground may even have those boxes..
