Attention! The balun i added is wrong, this type of antenna doesn't require the balun, i tested

the coil one and the 1/2 coax version and the perfarmance are bad, therefore connect the coaxial 

cable directly to the dipole element.

This antenna comes from the original author http://www.ab9il.net/wlan-projects/wifi6.html

but my materials are different. Another good thing i did is about

the wi-fi card that is outside just near the antenna to avoid signal loss, then i connected

all the stuff with a long USB cable. I protected the copper elements with PLASTIK 70

by Kontakt Chemie, this 'little' antenna lives outside...
