How much TV do you watch normally? How much TV do you watch on vacation? For us, the TV is usually not watched, we have but a handful of once a week shows we DVR and watch. On vacation we seldom turn on the TV, we read, watch nature, sit in the spa, talk with neighbors, and go to bed tired. TV is not important. Since we seldom dry camp most campgrounds have cable. Some don't, but they are usually close to a city (large town) and over the air reception is fair even with a most basic antenna. Wingard sells a flat sheet window antenna, about 14" square and presses against the window, which actually works well in city/large town environments. It's cheep, portable, and is available at CampingWorld, Home Depot, and I'm sure other hardware stores. In my previous RV, just sold after 10 fun years, I don't think we had the "batwing antenna" up twice.
Happy Trails.
