i suggest you look for the experiments
of the "OHF-GROUP MUNICH" or DJ9HO

There is a variation of the Quad where a mesh is placed behind a
circular driven element and optional horizontal elements are placed
in front.


There is a book published showing their builds
and the results measured n dB's comparing each variation.
i dont know the name of the book though.
It was published in English as well.
