Several years ago, satellite TV became popular among RVers, thanks to small, portable systems with 18-inch satellite dishes, which could easily be set up almost anywhere. These systems have opened up a whole new world of entertainment to RVers. No longer do we have to settle for what we can get with a regular antenna or have to look for a park with a cable hookup; instead, we can choose from hundreds of TV channels, available in virtually any location in the continental United States. You can even enjoy satellite programming while in motion, thanks to the TracVision dome-shaped satellite dish, which automatically locks onto and tracks the satellite signal as you drive along.
