    Half the WiFi world seems to have latched on to the Poormans USB WiFi
    "scoop" antenna idea we rustled up mid 2004, with ~1000 hits daily
    still averaged at the resource page => www.usbwifi.orcon.net.nz

    To suit situations where such Chinese cookware WiFi antenna may be
    -ah- "visually distracting", we've rustled up a more professional USB
    WiFi parabolic design based around cheap cooking sieves and a flexible
    stalk desklamp base. See pix & Netstumbler testing graphs =>
    www.usbwifi.orcon.net.nz/mk2wifi.jpg

    Performance, measured with NS,indicates 12+ dB gain over a bare USB
    dongle- the classic " scoop" gives more like 15dB of course. When
    spray painted black, the Mk.2 setup looks almost invisible & could
    easily be used in a library etc with ones laptop - cover with a
    plastic bag or jersey perhaps for discretion. Bill of materials
    ~NZ$15, with parts readily available via "The Warehouse" etc.
