The only 'hobbyist' antenna which we've had very good milage in actual production use on in www.wirelessleiden.nl is the quad. Virtually all others, even the simple slotted wave guide requires a professional toolshop create due to the tolerance. Anything more complex seems to require a full calibration setup to tune. For verified instructions on the BiQuad antenna use version 0.2 of the PDF: http://www.wirelessleiden.nl/wcl/cgi-bin/moin.cgi/QuadAntenne Dw
