Hi everyone, I have acquired a slightly dated Power Mac G5, and went to buy an Airport Card for it. Well, when I went to install it, the instructions that I downloaded for my version. (Dual 2gig, a few years old) says something about attaching an Antenna to a port on the back. The antenna is installed but the airport does not have a signal. I do not have the antenna for the port on the back. Does anyone know how to acquire the antenna for this model? I have searched the Apple site, but can't find that product or anything about this issue other than the manual download, which states that it needs the Antenna. I would appreciate any help in this matter. Thanks.
