I live in a camper at a rv park. My tv and sometimes my phone has a hard time getting the wifi signal from the Parks wifi. I've seen where you can buy a wifi extender and the Parks owner told me he bought one to extend his signal... But what about a device to boost the signal I am receiving inside my camper? Is that the same device? However I understand that I need something to receive the signal and I'm understanding this device puts out a signal....
