Materials needed for this experiment
Before you start, caution is advised . Directly manipulating the mains current is out of the question! The trick is to exploit the earth circuit via a specific assembly, without contact with the live terminals.
Here is the list of essential items:
- A standard male plug (extension cord type)
- A coaxial cable (same as that used in TV installations)
- A coaxial connector suitable for your receiver
- Possibly a drill and electrical insulation
Step-by-step guide to assembly
- Prepare the socket:
Use a blank plug (without connection to the live terminals). Keep only the ground pin (center position). - Connect the cable:
Connect the end of the coaxial cable to this ground terminal. Be sure to insulate the other conductors well. - Connect the device:
Attach the other end of the cable to the antenna input of your TV or radio. - Test the device:
Insert the plug into a wall outlet… and check the reception quality!
Explanation of the physical principle
The secret lies in using the ground network as an improvised antenna . Your entire electrical installation then transforms into a vast receiver, a bit like a metal screen capturing the surrounding waves.
Note, however, that performance varies depending on several factors: quality of installation, electromagnetic disturbances, and proximity of transmitters.
