Actually it works pretty well for what it is. I have included some MP3
samples on the web site. Have a listen. The mic was pointing upward at
the time of the recording. The parabolic setup, because of its
directionality, will attenuate some of the ambient sounds and boost
others. As for wind noises, the parabolic dish may help or hinder
depending on the direction and speed of the wind. In some positions it
will serve to create turbulence around the mic element that might not
have been a problem with the mic alone. By the way, the unbrella used
in this model is plastic (vinyl I think), not fabric. That makes it a
little more acoustically opaque to sounds coming from the rear,
especially those at the higher end of the spectrum.
I loved your CD web page. Thanks for sharing that with us.
