Peter,
I used one-tenth mil polycarbonate film, because I had it on hand. It was c=
alculated to not start rolling off until 40 kHz or so. one quarter mil Myla=
r film is easily available. =A0But that doesn't alleviate the difficulties =
of purchasing small quantities of film.
What sort of microphone capsules are we talking about here?

 =A0   Eric, can you give some more details about this technique? How thin =
does the film have to be? How far from the capsules should it be? What effe=

I've been using an upside down rectangular plastic lid over my SASS, held o=
n with elastic cords attached to the corners and down to the tripod legs. T=
he tight cords put it into a bowed shape so water runs to the edges, then t=
he water runs along the edge channels of the lid, and down through the hole=
s I've made for the cords, then down the cords. No attempts to dampen the s=
ound yet, I'm happy for now just to protect it from rain.
