Mine fits perfectly in a window with an arch right next to the computer it is connected too. I wedge it in there behind the blinds and get clear signal to the end of my street, about 1/4 mile away.
Mine was sitting on top of the computer that was on a card table in the basement. I didn't like losing reception when turning around in my cul-de-sac, so it now rests 2 feet higher, on top of a spare TV (still in the basement).
Mines connected to the back of my transmitter. I get about a half block of clear transmission. Of course I can hook up my true match antenna and transmit about a half mile but they can't see my house that far away.
