Hello. Trying to help a young couple who can't afford a monthly cable/wifi bill. They currently have an outdoor antenna to pick up a few channels on their tv, now we are working on getting them wifi. Thought about purchasing an outdoor wifi extender/antenna to pick up the signal from the office of the campground they live at. They have permission to do so, it is about 150-200 yards away. They have no computer or laptop . They have an x-Box and TV. Need to find a way to set up the wifi antenna to provide wifi in their camper to stream Netflix and get wifi on their phones. Can this be done and if so what do we need? Thanks
