Drawings from elk again d-link 1800.rar but on lan23.ru You can find another two files which may be the same - I’m not shure.

I’m not sure but, this antenna will be hard to reproduce because we do not have info about thickness of substrate nor dielectric constant of the material. So this is not a option to build and test for me right now.
Some strange and scaring pictures found in the net.
Feeding 4 biquad whit coax line is something that seems to work and well tested, but this thing here look CRAZY! Feeding EIGHT biquads is something really looking strange at first moment.
