Is this possible?????????????????????

I want to use a Wifi Booster (http://www.amazon.com/Alfa-Waterproof-Outdoor-wireless-Integrated/product-reviews/B003ILWRLI/ref=dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1) and I want to hook it up to a router, it connects via usb, can I do this, because the antenna itself probably requires you to select what network you want. So what do you guys think about this?
