Check out a Bear Extender outdoor/indoor antenna. It works really well and it cost around $69 with lots of mounting options. I'm using it right now in Lakewood RV Park in Myrtle Beach SC. You connect it via usb to a laptop then turn the laptop into a hot spot and connect the rest of your devices. Only one signal bar without it and no connection possible. With it i have four bars and able to watch Netflix, YouTube and access my slingbox.
