cantennas are cool and they definatly work, the only catch is that you need to have the ability to screw in an external antenna to your access point, or have an antenna jack on your wifi card (orinoco has this)
they are not hard to make, it's just hard to get the parts you will need a bulkhead N type connector that you can solder the antenna into you will need a pigtail for your access point or wifi card you will also need some patience and soldiering skills also, the math on this antenna is VERY important (any math is important when you are dealing with 2.4Ghz because 1/8 of an inch makes a huge difference at those frequencies) Here is a good guide on building them http://www.turnpoint.net/wireless/cantennahowto.html Adam J.
