We where in St. Joesph Peninsula SP in Fl and had no reception. Went to town and bought the add on for the wiengaurd batwing. Did nothing. Took it back and bought a "Jack" from King. Got all the channels available. So impressed I bought one for home in my stick and brick house and got rid of a 12 ft aluminum antenna that was marginal at best. And it has little led lights to find the best signal before you start the station scan. Really works good and saves so much time
