Had to get a new Wilson, my old one did not do 4G LTE. Working good, and very “sleek” and small! Brings up the bars, and speeds things up. Of course, there needs to be a signal in the first place, it can only amplify what is there.
Hawthorne is on Highway 95, sort of NW-central Nevada. You can camp for free at the El Capitan Casino, which has a dump station, also at Walker Lake (free, or cheap) There are also paid campgrounds in Hawthorne, as well as in nearby Mina.
