I got it now, luckily what I bought has a wire soldered to the plates, I also done a little experiment of my own....the halostation against Alfa AWUS036H....its seems halostation has a little advantage over the Alfa, as you pointed out that aiming the halostation to the target AP has improved the signal...and I noticed that halostation is a little bit faster connection than the Alfa...but both units has the RTL8187L chipsets...
