Does anyone know details about the specific material the GPS shield is/was made of? It's sold out on 3DR's site, and I wasn't keen on spending $30 for it anyway (got the first one for the more reasonable $15).
A Google search turns up a myriad of EMI/RF absorbing sheets, but they list specific frequency ranges. If anyone has an idea what frequency range 3DR's shield was blocking, I could probably find equivalent material.
