Klas:
Yes, I would love to see the drawing.
Tonight I'm experimenting with a possible stereo MKH 20 mikes-with-barrier
setup and comparing it to the Stereo DAT Mic, both without mounting in the
parabola.
My simple test is to put a ticking windup clock in a quiet room, then muffle
the ticking with pillows so that I can just hear it several feet away. Then
I test each mike's ability to discern the ticks at various distances. The
trick is finding the point (= distance from the clock) at which the noise
floor of each mike setup completely obscures the ticking. This is my
poor-man's noise-foor testing technique.
Differences of around 3-4 db or more really show up when I perform this
test.
If the stereo MKH20 setup is clearly superior to the Stereo Dat Mic, then
I'll have to figure out how to mount the double-mikes on one of your dishes.
