Depending on the TV it should be "plug and play".
Cable TV systems in most parks are analog so you set your TV for "cable" and do a search. For antenna you need a TV with a digital tuner and set the TV for "antenna". There should be a panel on the wall with what looks like a car cigarette lighter. That panel will have a little push button and when the button is "in" a red light comes on. That is for using the antenna for over the air digital stations.
