Yes, I know Andrew, when I built the first one about twenty years ago 
from the plans in the Amateur satellite manual using their 
dimensions, I built 5 iterations, before I got it flat at 435...But 
then it scaled perfectly to all other frequencies....

And as near as I could measure, they are all 1.8 or less...The filar 
length is critical, the bends can be approximated...
