Re: Faraday cage

I used "chicken wire" screwed to 3/4" pvc fittings. Lace
a braid (like RG8U coax braid) through netting to corners.
You could put together an enclosure like a dog run for
probably less then $30.00, and in can be clamped or
screwed together with wingnuts.

Was very effective in keeping high energy RF/arcs away
from me.  Cut off frequency is 1/2 wavelength of longest
opening if memory is right, so would probably be
good up to several hundred Mhz.  FWIW.
