this is the 1st. version of my usb wifi antenna. it has been inspired by:http://www.instructables.com/id/EQARE4I72GEPUCHTHU/http://www.usbwifi.orcon.net.nz/
i did not have immediate access to "Chinese parabolic cookware" however i will use one next time. instead,i used an eight inch strainer , without the strainer i do not get a signal in my house. this entire instructable has been uploaded via the strainer/usb antenna.
