I do wonder how good my dungeon would be if it was converted into an RF anechoic chamber?

Only problem I see is any emergency lights etc the building requires might create RF chatter.

If I was serious then it would be shielded and the incoming mains would be filtered. Lights would have to be converted to pure DC driven LEDs
There is another level below, but I suspect that might have metal shielding inbetween like the roof does. The concrete on the side is physical earth soil as it's underground.

But you'd need to spend north of US$ 100k to build a good one. A TEM cell is cheaper / less work and you can create very strong electric fields inside with relatively little power. Nice for testing immunity.  I'm planning on building a reasonably sized TEM cell myself in the next couple of months.

Yeah, but not as cool looking!
IIRC AVX had something like this, Ron Demcko really talked up the software side of it, might talk to them.
