See what's hidden in the bushes outside our hotel window? It's an 11 element yagi antenna, for pulling in the distant signal of the hotel's router located on the other side of the block. I used this with a dd-wrt configured fonera to convert wirless to wired and run that into a switch for VOIP phone, then attach a secondary router to transmit a powerful signal as an AP device in the room. The miracles of electronics!
