Ours has a booster built in, with a button that you push (and green light) right on the panel where the TV connection is made. When on it makes a huge difference, though still limited range. We get nothing without it on, about 5 channels with it on and that's at home. I doubt it would get you anything with the tower beyond about 30-40 miles away. We installed a smart TV and use a wifi hotspot on the iPad air if the park doesn't offer wifi.
