Globe Tattoo & DIY antenna

I'm looking for a way on how to improve the reception of my Globe Tattoo modem. And luckily I came across this simple, yet effective, solutions (USB adaptors & DIY antenna = "Poor Man's WiFi" ). 

Actually I tried using an aluminum casserole cover and I saw that my modem gained from ~89db to ~72db. Which I think not bad for my testing purpose :)

I'm planning to improve my antenna based on the samples and information on the website I mentioned above and I'll post an update as soon as possible.
