Dave just bought an RV and he's looking for a booster for Wi-Fi and 4G Internet reception. Leo says truckers use Wi-Fi antennas and many have magnets. As for 4G, Leo says he won't really need one for that. It either works or it doesn't. And in areas of limited reception, the chatroom says that Weboost makes them for $200. It's essentially a 4G repeater.
