Once again, i tested several wireless design.
The spider is a simple to do (really), quarter wave omni-directional antenna. The cost: a female N :) Beside this antenna doesn’t have any gain, it prove to be really usefull, mainly for wardriving because it’s small, and offer really better performance than the default PCMCIA builtins (because it’s a omni and this is very good for out-door use)
This one require a little more job. The design came from gumph website. In fact the main issue with this one is to cut the parts at the good size. I made a 8 parts one, and give me ~ 6db. I will add 4 others soon. More infos can be found here
