I used an AirPort antenna set from a clamshell iBook, fed cable out through hole punched into rear of case, taped antennae to display back. Pic not current, but gives basic idea: http://mywebpages.comcast.net/macdan/images/ti_wifi.jpg
thats intersting. Looks like you have the same setup as quickerteks whip antenna but without their $120 bill. I would venture to guess you get a lot of odd looks at the local starbucks tho :P
Hmm far as I know, the airport norm card, and the airport extreme card are the same external port... I haven't compaired them side by side, but I do know the airport norm card's cable does fit in the extreme card. The main diff, is that the norm card is larger, thus more space in the compter... but is the same size as the pci slot, on both ti, and al. g4 books...
oh and dankephoto, do you live in CO? I noticed the comcast.net... be funny if we knew eachother... lol
