For the homemade microwave detector I tried different types of antennas and finally I came back to the circular antenna because it is the one that gives the most satisfaction for the moment.

I put on dailymotion ( http://www.dailymotion.com/Maximus_Leo because I couldn't put them on group / econologie !!!! ??? ) some short videos showing the electromagnetic leaks of a microwave oven at the door, at the ventilation level (where the level of leaks is maximum), the electromagnetic radiation of a GSM mobile phone at the time of connection (fifteen seconds after switching on the signal reaches a maximum level for a few moments), the radiation in communication, and the effectiveness of a simple sheet of household aluminum placed in front of the keyboard which divides the radiation by 10 .

The detector is also sensitive to the 433 MHz anti-theft alarm signal.

In the FR2 news? hie, David Servan Shreiber said that the emission was maximum on the back of the laptop, so it is best to put the laptop in his pocket if turned on, keys facing the body.

Have you tested the back side of the laptop?

In another report on Special Envoy, a lady from Paris covered her apartment with aluminum sheets including doors and windows: headaches disappeared. It is surrounded by GSM and other antennas in the neighborhood.

it therefore confirms that the aluminum protects from these GSM radiations.

Leo, you need to join the group on this page: http://www.dailymotion.com/group/econologie
After you can propose directly in the group during the upload.
For those, I invite your videos to the group.

Funny how your sensor "varies".

ps: you want me to show you all your videos in one? because small sessions is a bit painful to see ...

In my message last Thursday I wrote that the measured signal was about 2 times stronger on the back of the laptop and that it may have been wanted by construction. So what David Servan-Shreiber says confirms what I saw. On the other hand, he does not say that when the line is taken there are very strong impulses and that a shielding system, a simple metal sheet inside the phone, on the keyboard side, would greatly reduce the radiation.

I would have to make better videos because there were lighting and reflection problems.

It should be noted that this detector works without a battery, therefore only with the energy captured by the antenna.

Who has already tested this detector? https://www.econologie.com/shop/capteur- ... p-174.html

according to the customer opinion, it is not calibrated? https://www.econologie.com/shop/capteur- ... ews_id=196
