<DIV>The tangents that some threads create are often much more interesting
than the original intent of the thread. </DIV>
<DIV> </DIV>
<DIV>Keith I would say it's not a good idea. If you built a fuse out of this
material, (done everyday BTW), I suggest you build it large enough to
accomodate the person flying it (vbg). I know Bill, Don Ramsey and Al Glenn
and probably several more, flew or still fly "Faraday Cages" for a
living</DIV>
<DIV> </DIV>
<DIV>Now, how we went from measuring surface flatness to "shielding" devices
from EMI/RFI (regardless of what the emitting source is), is beyond me</DIV>

<DIV>John,</DIV>
<DIV> </DIV>
<DIV>I disagree. The definition of a "Faraday
<STRONG>CAGE</STRONG>", which is what Bill said, is a completely
conductive sealed enclosure.</DIV>
<DIV> </DIV>
<DIV>Also, the edges don't have to be fully bonded together for RF
protection. They can be stitched together at intervals depending on how
high in frequency you want attenuation. The closer the spacing, the
higher the cutoff frequency. Obviously, if you want cutoff up into the
gigahertz range, you pretty much need a continuous bond.</DIV>

<DIV>That's what it is. No RF gets in or out. Something like 110dB
attenuation.</DIV>
