Radio signals

[kermit911]

Is there a way to block any and all radio signals. RADIO, TV, SATALITE, BEEPS, ETC. Everything from entering a room? What kind of material? Will Lead block every kind of signal?

Thanx

Sure, just construct a Faraday room or cage as depicted here:

You need what is called a Faraday Cage.

As I understand it (not being a professional) it is a 'cage' IE walls, floor & ceiling, made of an electrically conductive material (doesn't need to be lead - you're thinking of nuclear-type radiation). Whilst solid (IE sheet) will work, it doesn't need to be and a mesh, providing it is small enough gauge, works adequately.

See en.wikipedia.org/wiki/Faraday_cage (<a target='_blank' href=en.wikipedia.org/wiki/Faraday_cage>en.wikipedia.org/wiki/Faraday_cage</a>) (My first attempt at a link in AB - hope it works!)

And it didn't!

As the above say, just a metal box.

It's why your mobile phone may not work if you're in a lift (or elevator, depending where you are).

Are they beaming signals into your head?

yep Faraday cage

a cu wire cage will do.

Good tv prog of a fella who had made one, looking a bit like a chicken wire coffin. who took his transistor in with him, on tv and as soon as he shut the door of the cage, the transistor went silent

v effective demo

will it block every sort of wave ? no pressure waves of the air, will go through and so will light waves.

It is very easy to block any kinds of radio signals like Radio, TV, satellite, Beeps,Etc with the help of hardware like Master F2800 which is helps to detects all LF, HF, VHF, UHF and microwave signals, it also receives all devices that emit a radio signal between 0.1 MHz and 8.0 GHz (8000 MHz).
