Wireless hacking

So my shiny macbook pro that I was promised with the new job turned into a battered R50e Thinkpad. Ho Hum. Still at least it has built in wireless.... hmmm. maybe not. Enter a Cheap n Cheerful Edimax EW-7108PCg PCMCIA card. Works fine under linux including kismet using ra0 - it's the rt2500 chipset driver.

However I'd like to make use of a decent external antenna for better range, so opened it up and discovered the antenna consisted of 2* 18mm tracks with no obvious points to solder in a pigtail.
