OK I stopped drooling. It sounds promising but a bit pricey (120$). However….I am a little doubtful on the range of a mile. It looks like its only powered from the PC’s USB port. No external power supply…so I question if they thing would get enough juice to extend the range it claims. And for 120 bucks…I could by a yagi….
