Hi all,
I'm now very busy trying to findout how to block external RF at my apartment room. I'm on 23rd floor. A huge radio boardcasting tower (714KHz, 90MHz) is just 20 meters away running along with my building. It's higher than 25 floors.
I know that many GROUNDED conductive surface can shield the room. unfortunatly It's imposible to find a ground on 23rd floor (Except building electric ground)
So my question is
1. If I shield the room with, say, aluminium plate, without ground. The protection will be less but how much?
2. For no ground, I think of finding other material. LEAD!. Lead can block gamma, X-ray. It should more effective in shielding RF compare to other material, is it?
3. What material can I use for the windows (Glass)?
Thanks so much
