This simple antenna brought me from hovering around 90db constantly to ~78db only fluctuating to 82db. Hope this helps other people as it did me, I'm 16 and have been looking for a way to improve internet speeds for my gaming and this finally did it. Feel free to ask questions, i'll answer any that are reasonable. (P.S. You don't need to attach the wire to the card/phone it creates a field around it that gathers the signal for you. Though attaching it may help, but i don't want to shell out the cash for an adapter and Low loss Coax cable)
