Smaller holes blocks even higher frequencies. With no holes not even light comes in.

No point. In the event of an EMP the whole grid will go down. Better to keep a generator.

​@ObamaoZedong I think you'll have bigger problems if someone drops an emp then your phone getting bricked 😂

Forget wire mesh or holes. Why did he even PUT holes in his aluminum foil covered carboard box. Does his radio need air holes to breathe? He's presenting disinformation. All you need is a metal box, or a 'small', cheap metal garbage can, from Lowes, Home Depot, Target, etc. Test the container by putting your cell phone in it and use another phone to call it. If there's no connection, it works.

​@@tjmmcd1 ghislaine Maxwell tried using aluminum foil to wrap phone... She still got caught.

because we are radios! :O

I'm a 5TH Dimensional Being and we can change our vibrations and change our wave lengths. A silly fairday is no match for my powers Mwa Ha Haa jk!!

Exactly and dad put foil on the antenna to amplify the signal. I'm so confused 🤔

@@GigiBellia could be the foils direct contact with the receiving antenna. The cage traps the signal, but wouldn't if the signal had a path to travel.

Aluminum foil is a conductive material, as most metals are, and increase the surface area of the antenna by absorbing the electromagnetic signal (radio waves) and conducting it through the foil into the tv antenna. Think of the antenna like a target, and the radio wave like a bullet coming out of a gun. It’s hard to hit a small target, so adding aluminum foil to make the target bigger makes it easier to hit. Hope this answers your question.

No actually, they are not small paraday's cages. They actually absorbed part of the signal and sometime redirect them (at least the invisibility to radar technology on stealth aircraft) making the whole aircraft vanish or become a hard to hit target (when applied on ships, with special hull geometry, the ships would have the reflected signal on radar as small as a fishing boat. Radar could easily lock on and shot down small target aircraft if they cannot proper communicate with it, but no way in hell they would do the same with fishing boats, since wouldnt have proper communication)

in military, they use parade-day cage. * slow laughs *

Great question!!

Should be smaller than 6 meters across. Lol don't be fooled by the 5G scare tactics it's harmless anyway.

Experiment yurself Discover what works by experimntation Or dont have any holes Use tin foil etc Or pin size holes

Why what are you doing that needs to block 5G. It's just the same concept just thicker mesh walls. We use it to block all outside connections to test Bluetooth devices that we developed and outside connections can mess up our sensitive tests

Install a metal roof and radiant foil barrier insulation. Change your windows to the low-E glass. None of this will matter if you can physically see the cell tower, but it will all attenuate the signal.

@@rgbcolor6450 I tried all that. No luck. But thanks.

Faraday cages are only effective in blocking radio waves within the confines of the cage. If you are interested in disrupting radio or cellphone signals within a designated area, you would need to procure a “jamming device”, which is a device that emits powerful radio waves with the intention of overriding weaker radio waves. In this example, think of a radio wave like a small speaker playing music, and the jammer as a large speaker. When the large speaker is off, you can hear the small speaker, but if you turn on the large speaker, the small speaker is still making noise, but you can no longer understand what is coming out of it. Additionally, please be aware that certain uses of jamming devices are illegal in different states and countries, and it is within your best interest to do research on your local laws regarding jamming devices, where to procure a jamming device, and how to optimally operate one. Hope this answered your question.

@@chutemi. Thank you.

How about instead of tricking people why don't you speak to them 😅 saves you money and time 😂 We used the trick of we are playing a quiz, hand over you phones then we put all the phones in the kitchen and never gave them back out until the end

I think you'll have bigger problems if someone drops an emp then your phone getting bricked 😂

I bet he used the front camera of his phone

Ty.

maybe because the cardboard inside

My guess is because the cardboard is insulating the radio from the foil.

My guess is that it's because you created a conductive path with the foil and antenna, thereby essentially making your antenna bigger. But the radio is inside the box but not connected to it in a circuit. So the EM rays are caught by the Faraday cage and never get to interact with the radio.

Aluminum foil is a conductive material, as most metals are, and increase the surface area of the antenna by absorbing the electromagnetic signal (radio waves) and conducting it through the foil into the tv antenna. Think of the antenna like a target, and the radio wave like a bullet coming out of a gun. It’s hard to hit a small target, so adding aluminum foil to make the target bigger makes it easier to hit. In this scenario, the foil is not connected to the antenna of the radio, so the waves that are absorbed have no way to conduct into the radio antenna. The foil surrounding the box acts more like an absorber, taking the energy from the radio waves and grounding it, preventing it from reaching the radio antenna. Hope this answers your question.

No, they are not necessary. He only demonstrates that you can also have holes in the box, as long as they are smaller than the wavelength. For example, microwave ovens also have holes that allow short-waved light (400-700 nanometers) to pass throw them, while also blocking the long-waved (~12 cm long) microwaves radiation. Another example is the elevator, where your phone signals can get blocked without having holes in the elevator. So no, it's not necessary.

Amazon: No, we have better faraday cage made by TOP people, we can assure you that it 100% works. LOL

Lunk

Just turn the phone off ?

@@djcustoms6637 That won't work either, unless you can remove the internal battery, only doing that truly shuts a cell phone OFF.

@@geico1975 Okay what phone stays on when your turn it off ? Also why do you need it completely off grid

Doubt it, I tried to use aluminum and it didn't block it's cell signal

A galvanised bin with lid would work more effectively under most circumstances. However, don't forget to make sure that the gap around the inside of the lid has some kind of conductive material sealing it so that there is no break in continuity between the body of the bin and the lid.

@@cockle0979 I was told it has to be ground, or it won't work.

@@manatarms79 what does "ground" mean. I've been trying to find definition online but not very clear in context of the faraday system. How would you ground a system and why won't the cage work without it being grounded.

@@COLDoCLINCHER37 a ground is grounding the circuit to the ground. An easy way is copper leads to the ground from the cage or just build the cage on the ground.

I think you'll have bigger problems if someone drops an emp then your phone getting bricked 😂

works also for higher frequencies (smaller wavelenght)

??????????????????

No, use a secure internet network. If you’re forced to use public or unencrypted WiFi, I suggest using a VPN, which is a service that encrypts your traffic data. Mobile carrier connections are encrypted, preventing others from viewing your traffic. Additionally, most applications with large importance, such as banking apps/websites and even Google already encrypt data moving from apps and websites before transmitting it into traffic. Hope this answers your question.

😂😂😂 no of course not ? How would this ever protect you

So you are your own grid

Starlink

@@patrickduncan346 🤣🤣🤣🤣

A faraday cage blocks minute electromagnetic radiation, typically in the form of a radio wave. The intention behind the faraday cage is not to shield against electromagnetic pulses. If you are concerned with your electrical grid going down from an EMP, a very unlikely scenario, consider investing into a personal generator for your property. Hope this answers your question.

I think you have bigger problems if someone drops an emp then your phone getting brickes

Not needed for small stuff like normal radio signals. Against solar flares it's probably better to add a ground but I haven't done the maths.

Solar Storm event.

You want to protect them from the PULSE . IT'LL FRY THEM !!!!!

A faraday cage blocks minute electromagnetic radiation, typically in the form of a radio wave. The intention behind the faraday cage is not to shield against electromagnetic pulses. Most EMP weapons are not designed to target specific households or private properties, but instead disrupt electricity production or distribution by targeting generation sites and distribution centers. Additionally, the majority of war or terrorism related electricity disruptions occur from physical munitions or explosives which directly destroy the site of electricity generation or distribution, exacerbating the period in which electricity is unavailable.

@@djcustoms6637 100%

Sone devices will work and some wouldn't because the cage dosent stop all the signals

In this example provided, the use of the faraday cage only works when the receiving device is placed directly inside of the faraday cage without any conductive materials acting as a medium emerging from inside the cage. In this specific video, the proper usage of the faraday cage occurred from 0:28 to 0:32 where the vast majority of electromagnetic radiation was blocked by the cage.

to be fair he proved it with recordings of this video

This isn’t necessarily true, as a faraday cage can work without any materials between the metal and receiving device, so long as the receiving device does not have a direct conductive connection to the cage. MITx Videos has a publicly available video on their KZfaq channel titled “Faraday Cage” where you can view an example of a faraday cage constructed entirely out of conductive metals working without any “buffering material”.

You may also be confusing a faraday cage for a dampening material, commonly lead or concrete, and sometimes water. Dense materials such as lead and concrete are able to block electromagnetic radiation, most famously ionizing radiation, by directly absorbing the energy from the electromagnetic wave.

The brain does not receive stimuli (information) from radio waves, and thus there is no purpose for a tinfoil hat. Additionally, tinfoil hats lack any substantial mathematical or scientific evidence proving that they are effective in blocking electromagnetic radiation from reaching the brain.

Tinfoil suits and no not really

Trees , rain , compact disc , lead paint

Same principle; you're just blocking a different wavelength. So, if you do the math, you need a conductor with holes no bigger than 6mm.

Why what are you doing that needs to block 5G. It's just the same concept just thicker mesh walls. We use it to block all outside connections to test Bluetooth devices that we developed and outside connections can mess up our sensitive tests

​@@djcustoms6637conspiracy nuts trying to block 5G evil signals

If the hole size is smaller than 2 inches you are covered from 450MHz to 6GHz. The higher the frequency the smaller the whole has to be.
