You don=E2=80=99t need a multi-pattern mike for the Side mike. Those can wo=

 in this application is a single-pattern small diaphragm bidirectional mike=
. My attempts with this technique used a Bruel & Kjaer (now DPA) 4001 omni =
for the Mid mike in the focus of the parabolic dish and a Sennheiser MKH30 =
bidirectional for the Side mike behind the dish, facing sideways with its n=
ull to the dish and its positive polarity side facing left. (David, I=E2=80=
=99m glad to see I=E2=80=99m not the only one willing to place mike[s] behi=
nd the dish!)

A number of recorders and mixers offer Mid Side decoding to Left Right for =
recording these days. A smaller subset of those let you decode MS to LR int=
o the headphones while recording the undecoded Mid and Side signals. Then y=
ou can decode MS to LR in a DAW app. There are plug-ins available in many f=
ormats for doing that, or you can just do it by duplicating the S track in =
your DAW and flipping its polarity. Pan the Mid track to center, pan the or=
iginal Side track to full left, pan the dup Side track to full right. Link =
the level controls for the two Side tracks so they match. Raise the Mid tra=
ck or lower the two Side tracks to narrow the stereo image, do the opposite=
 to widen it.

In the desert, absent wind, you=E2=80=99re dealing with some very quiet amb=
is, so low noise mikes and recorders will help your efforts there. And a tr=
ipod mount for this strange MS dish contraption is advised. Your breath and=
 other body noises will be very close to that Side mike if you=E2=80=99re t=
rying to hand-hold the rig.
