I've seen numerous CAN-tenna projects. I built one and didn't really notice an improvement. It wasn't very pretty though. I suppose if I did it right it may have worked better though.
:haha: Hahaha, that reminds me of all the cantennas me and my friends would make at this one friend's house. We would have lan parties in his garage, but the wireless router was in the actual house so the signal was awful. We would all set up cantennas with wireless adapters and play CS 1.6 through all the insurmountable lag. Good times.
