Hi Kim,
Here's a little more detail on my array.  I created it as a way of
providing flexibility in arraying four microphones.

The decca was created for classical music recording so the spacing
between the mics differs based on the event being recorded.  For those
who don't know a decca tree is basically a metal rail, 3-5 feet long
(1-2 meters), allowing 2 or more mics to be mounted at varying
distances.  It is then easily hoisted into the air for concert recording.

As to how it has works in the field, I have generally been happy using
a two mic spaced omni array, which is essentially what a decca tree
is.  One does need to play with the spacing of the mics to get the
sound one is looking for.  It's all about experimentation.  One can
create a decca tree with PVC pipe, or the rail of a porch or two or
three adjacent tripods.

See my website for "gregga array" or "AB" recordings, these were done
in the style of a decca tree.
