Faraday Cage - Construction
The idea of the "CAGE" is that all the metallic material of each face and of the 6 faces of a rectangular parallelepiped, must be totally physically linked, (welded), between each face the 6 faces, and this one with good grounding , it is prn that if you have an element that works with electromagnetic waves and you wrap it in a metallic sheet, (aluminum foil, copper, bronze, tin, lead, etc.), the waves do not penetrate or leave, that's what called squirrel cage or Faraday. luck
Yes I understand. But I told you the same thing I said to Servimat1: no matter how much I connected it to the ground, the cell phone kept ringing, and that is what catches my attention. The battery-powered radio does cancel it. That's why I suspect that it has something to do with the frequency, and / or the thickness of the wire.
In fact, the opposite happened to me once. I wanted to run a UHF yagi antenna in an environment, in front of huge windows that reached the ground, but the antenna did not grab the channels (I know it worked outdoors), and apparently the fault was due to the fact that there was a metallic fence .
Hello, if to a bird cage, little one, you wrap it all in a wire mesh lunch box, the electromagnetic waves do not arrive inside, the one of your cell phone, it would be necessary to see where the antenna is with respect to your house, if it is 100 meters away . It has a lot of relative power, try to wrap it completely with kitchen foil, simple, and do the test, if it goes, "e'mandinga thing, you will have to study everything back, NOTE: do you have wi fi at home ?. luck
Yes, I have wifi. And very good data that, I had not thought about it. It would be something like that the frequency of Wi-Fi, which is at least 2.4 GHz penetrates the cage, and acts as a carrier of the 3G signal, even if they have nothing to do with Wi-Fi and telephone service? I mean, as something that happened.
I tried calling from a landline or calling me from another cell phone.
Now I will try to disconnect the wifi for a while.
Yes, I had tried it by deriving the cage to ground, but the result was the same. I see that in some videos of You Tube they achieve it with equal or larger plots.

Maybe the thickness of my wire should be greater.
And perhaps the frequency is related. It remains for me to try a battery-powered radio, which are lower frequencies, and may attenuate them completely, or at least to a greater degree.
