Well, I understand your problem. The Dell 1150 is just an ORNiCO card, if you look at my pics you see how i have something connected to the end of the card, look on the end of yours you will see a black circle, pop that lil thing out and you have your antenna jack. What you need is the pigtail(ornico)and the antenna, and then your set.
