I have never gotten less than 20 channels even in a bad reception area with just the batwing antenna that comes standard on RV's. Certainly no need to pay a service for TV reception in your RV! :C
>When you pull in look at what direction 'everyone has their antenna aimed'. Turn your antenna the same direction and start from there inching the dial to tune into the signal. With digital TV you have to move the antenna dial very slowly to capture the signal.
Some TV's you might need to rescan channels each time you move the antenna a substantial amount.
