Look up Faraday Cages on the internet. Everything you want to know about RF
proofing a room or work area.

Subject: [RFI] RF tight rooms - somewhat OT
Hi Gents,
I know a crystal radio enthusiast in CA that lives near a 50KW BCB radio
station. He's been having trouble making Q-meter measurements on some of
his hi-Q coils using a HP Q-meter. He's been making experiments with
various shielding methods using an AM BCB portable radio as a detector.
He says that the best he's found so far is aluminum foil, as long as the
"seal" is tight.
To make a room that is large enough for him and a bench takes a LOT of foil.
The floor, ceiling, walls, floor and a good seal on a screened door would be
needed for a really good RF room. The power for the room would also have to
be filtered or he could use a computer's UPS. The shielding would be
grounded, and the shielding, whether it's say, chicken wire, AL screen, etc
would have to be bonded together at the corners. Then the door would have
to be sealed as well (maybe metal weatherstripping for that?).
My question to the group is what, in your opinion, is the best/cheapest
RF-tight test room he could build for himself?
Has anyone on this list done that?
73,
Charlie, N0TT
