<<With all the interesting notes about cardioid vs omni in a dish,
has anyone tried a bidirectional (figure 8) mike at the focal point
with its positive side facing into a dish? Apart from the physical
difficulty of mounting a side address mike in a dish, it might offer
some of the stated advantages of a cardioid, but with lower handling
and wind noise susceptibility.>>

Could be interesting, but be aware that the back of a figure eight
mic is out of polarity relative to the front, so some degree of phase
cancellation is inevitable. However, it's worth investigating because
any given source will appear in polarity to the front at a distance
of a foot (or however deep the dish is,) & out of polarity at a
distance of many feet to the back. It might be moot given the random
phase relationship, or it might be really messed up having a source
appear both close & distant.

<< It certainly would give better side rejection than either card or
omni!>>

For sure.
