I recently put an airport extreme card into my G5 Powermac dual 2g. Problem is, I can't install the little T-shaped antenna on the back of the mac since the port for it doesn't actually line up with the card inside the computer (bought it used). At any rate, I'm looking for a way to perhaps hook up an external antenna by attaching some kind of third party antenna or antenna extention that would plug directly into the MC Card connector on the airport card itself. Any ideas?
