To test for minimum REQUIRED 50db protection, you DO NOT need to cover devices with foil or faraday bags. You only need a strong AM RADIO SIGNAL OR SCANNER. However, the only way to know how well it works for sure is with a spectrum analyzer, which most people can't afford. Nevertheless, if the radio signal goes away there is a good chance that the cage is providing about 50dB shielding.
A cellphone has a much stronger signal. If you put your cellphone in without foil and you can't call it, then your cage is probably protecting WAY above the minimum 50dB shielding. Don't expect that to happen, though. It took a bit of work, but I was able to seal my cage well enough to even block that cellphone signal.
To test for even more protection, try using 2 way radios. Wrap one in foil the way I did in the video. If it works, anything put in a faraday bag or wrapped in foil like I did, is likely getting about 100db protection! See Dr. Bradley's link below for more information...
NOTE: If the signal still gets through, you may have to create a better seal of the opening rim of the can. I have a can that has a looser lid. It is a larger can. When I put the tape around the opening, it sealed better.
You can also go to disasterprepar... to buy a special seal for this.

It's actually not rubber. It's plastic. It just felt like rubber to me because it is somewhat flexible.

Thanks for your comment.
Agreed. Some channels think they need to give a science lesson in the process.😅
Everyone knows what these are for. No need for the excruciating lesson.
Thanks for the video!!
For Tragetted indivisual how can make farade cage
Thank you for getting to the point with no nonsense descriptions.😊
Glad you enjoyed the format.
Thank you! I've watched so many videos that were about 5 times the length yet spent so little time getting to the main point. Vey concise and informative!
Glad it was helpful!
Straight to the point presentation. Inexpensive and effective. I will be making at least two of these. Great simplicity and affordability.
Thanks for watching.
Thanks! I just completed my Faraday Cage. I included a solar charger and 6 AA PaleBlue rechargable battries to use in a Baofeng battery that uses 6 AA battries.
Great job. Agreed...that steel bucket will stop RFI and most EMP dead in it's tracks. The rubber is what I what use on the inside...non-conductive. Or get a large 31-gallon metal trash can (Behren's $23 at Lowe's), a couple of their blue 5-gal buckets ($3/ea with lids). All for less than $40 and you can put A LOT of sensitive electronics in there.
Thanks for the comment. I had planned to get a larger one this weekend and see what I can do with it. I like the little cans too because space is a rare commodity at my house.

Winner of a video, been searching for "faraday cage security" for a while now, and I think this has helped. You ever tried - Tennorra EMP Esterification - (should be on google have a look ) ? Ive heard some incredible things about it and my co-worker got amazing success with it.
I asked Dr. Bradley that question, he stated he had tested a microwave oven and it had fair protection, but not as good as the method shown above,
Sounds easy
...but what are the best items to put in it? Thanks
I have a video on my channel that tells what I put in mine...
Good job on the video! Concise and fast but loaded with good info. Thanks for posting!
This a fantastic idea for a quick-to-deploy system. Grab the handles of the plastic liner tub, give it a yank and you have the contents. We have a larger system in a lined metal container. Some of our flexible solar panels will be stored resting against the insulative lining as a backup in the event other panels become damaged. We truly like your idea for this system so the larger container will not need to be unsealed, simply to get that small item needed that rests in the bottom of the larger container. Thank you for posting this helpful video.
Glad I was helpful...
@newhampshirejack: Are you willing to share who told you solar panels are susceptible to EMP damage?
Actually, no one knows any of this for sure, but after researching this, I have concluded, unless connected to the grid, they should be fine. Im sure if you look hard enough, someone will explain why they are not safe...
Very useful. I'm heading up to ACE when I finish my lunch. Thank you. God bless you and yours😊👍
I see people selling the idea of using a metal ammo box as a faraday cage. I don’t recommend it. I tried it testing it with 2 cell phones. The “shielded” one rang as soon as it was dialed. Looking back I suspect that it failed because of the rubber seal which helps keep moisture out, but can’t block EM radiation. I noticed your cage was sealed every where with metal on metal. Thank for your work and the demonstration.
Ammo box will work if you use the tape I used to seal over rubber, BUT dont test with cellphone! Its too strong of a signal. Use strong am radio signal. If that works, you should be getting at least 50db shielding, which should be enough.
I know the antenna needs to be on there for testing purposes, but when actually storing equipment, remove the antennas from the equipment. Something not a lot of videos mention.
Lithium381
Good point. That is how I store radios
Why do you have to remove the antenna? What about cell phones and other smart tech?
@@taxat10n1sth3ft The antenna is designed to absorb RF signal... so removing it while storing it will improve the protection of the device.
For devices like cellphones where the antenna is internal this isn't possible.
@@imxploring what about removing the battery when possible? Would that help protect the cell phones?
@@taxat10n1sth3ft Probably a good idea anyway. Can't hurt.
Now that I spent $30 on tape and sealed cardboard all up in the can, I see this. This is great. Now I know what to do if I need another.
Easy. Simple explanation. Great video. Thank you!
Thank you for watching...
Great idea and video. Thanks. We were trying to decide how to make one cheaply!!!
Glad I could help.
Thanks! Got a couple of these going for various pieces of equipment. The spares will be well protected.
Your welcome!
Thank you,this is the quickest and easiest faraday cage build ive found yet...with the exception of people trying to just use aluminium foil and zip-loc bags alone..lol...now I dont know if foil and zip-locs will work or not but I do know I'm not gonna trust it with my gear...this on the otherhand is a lot more what I had in mind..after I do this I'm gonna pack it with the gear I already have in my BOB as well as a lot of extra flashlights,headlamps and several 2way radios...fuctional flashlights will be a great bartering item in a post EMP world
BUG OUT BAG TIME= GREAT VIDEO BECAUSE I AM GETTING A LARGE GALVANIZED CAN AND SOME RUBBER AND CARDBOARD..SEALED WITH ALUMINUM TAPE..PERFECT TIMING I FOUND THIS VIDEO,,WILL PASS THIS FORWARD..THX
Great video but for prep purposes, I'd say a trash can or dumpster would be more beneficial. For an inexpensive bug out scenario though, perfect!
Thanks for all your work and contributions!
I'm using a trash can. Are you suggesting a larger one? They take too much room and are not mobile. I know some people use larger cans, but I prefer not to and dont have a need for a larger one. I have a few small cans I easily store in my closet, attic, or garage.
You have to be kidding about a dumpster. I wont even bother replying to that.
I have several videos about this you may want to check out.
Again, thank you for taking the time to watch.
@@LoneStarPrepping I could go on and on but no, I'm not kidding about a buried dumpster or better yet shipping container.
As our magnetosphere continues to deplete exponentially and our poles shift 40 miles a year, we need to think BIG and fast. Consider the level of radiation that could be avoided...
*Don't be confused, I do agree with you in many ways and I appreciate you! Thanks again for the great content!
@@coreymason3272 You are talking about something that has nothing to do with my video. Sorry, I just think what you are saying is completely impractical and not necessary and virtually no one will do it. Im not overly concerned about the disaster you are worried about. Also, you said for bug out situation my can would be perfect. No, actually it would not be. Im not packing my can in my bug out bag.
@@LoneStarPrepping Hey fair enough, no need to be sorry! I'm guessing we're simply preparing for different situations. Admittedly, I'm a bit obsessed with the continuity of humanity and believe it is currently in great danger on multiple levels. Arguably the most likely and dangerous threat is an EMP/WEMP or a CME. Beyond that, our magnetosphere is depleting far more rapidly than expected.
Either way, best of luck and God bless you and yours!
OMG it’s so nice to hear 2 folks disagree with such respect. I hope if SHTF you 2 are representative of the new world order haha.
Thanks again
Thank you so much! I think everyone should do this, now I can and you made it easy. Bless you!
But why
@@adizivojevic8635 So if their is an EMP your electronics don't turn into expensive bricks.
@@adizivojevic8635 if your from the former Yugoslavia then u should know why.
This is very helpful. Question: how long would you need to keep your phones, insulin pumps, etc inside a cage like this, if there was an EMP detonated, before it is safe to pull them out? And how much notice would you estimate that we would have to get everything in there?
No idea. I expect there to be at least a couple attacks spread out if it happens. Thats why I have a few of the same items... 2 is 1 and 1 is none.
Prep as if you have no time. Like he said make a couple and put back ups to the backups in each one. Make 2 and use one after and if there’s another get the 2nd out. Who knows if these will work but it can’t hurt to try.
Quick to the point, well done😀
Caroline Brown
Thank you
Great video, right to the point. Well done and going today to get my 3 items to make mine. Thank you again!
Glad it helped!
This may be the option I use but different Faraday cages block different frequencys this option although very good will not block all frequencys. I'm no expert but im thinking of having a box welded together for me big enough for 3 or 4 medium solar panels and hid it but until then use a can similar to yours.
I saw a good comment on a similar video from someone. Prepare for an initial EMP attack. Then another one to take out any other existing exposed electronics later. Could be useful information.
Yep... I said the same thing in a couple of my other videos regarding EMP and faraday cages. See my video on "The 7 most important things to put in a faraday cage."
Great info! So much more affordable! I would venture to guess you can place inside multiple items you like to protect?
Check out my other video that shows what I put in...
Definitely useful. Thank you for the short and sweet video
Sure appreciate your quick, to-the-point videos. Time is a valuable commodity.
Does it have to be silver tape or can It be black tape
Trying to convince my parents to prepare but nobody listens to me
My people as a whole are more worried about status than survival because they can’t imagine a world that’s different from the one built for us even if that reality is swiftly being thrust upon us we’re-
Edit: Not that intelligent when it comes to Survival, besides myself and only in the least amount of importance.
Needs to be aluminum or copper tape.
@kamii, keep prepping! Buy extra drinking water, canned & packaged food, etc.... When disaster strikes and you have 3+ days of food your family will thank you. When I try to explain why it's helpful I use 2020 as my example. Not everyone is into 💩 hitting the fan prepping but when I talk about the stores being stripped in a natural disaster, pandemic or the family getting sick with the flu. If no one can shop it will be nice to have electrolyte drinks/mix, soup, pain reliever, etc.... People tend to be more receptive when I use an experience we are all familiar with.
I hope your family becomes receptive to your ideas and help prepare for what may come.
What happens if you spray the entire bucket with spray on rubber?
Should be fine. I almost did that myself.
Excellent! Thanks!
Thanks!
You bet!
going to try this with my daughter first. the science fair.
Cool. To test it, just use an am radio turned on to a strong signal. It should go away when you put the lid on. If it does, you should be getting about 50dB shielding, which is all you need. No way to know for sure without some expensive equipment, but it will be close. To get best shielding, do the aluminum thing I showed in the video.
Metal lunchbox or fruitcake tin for smaller items. Lined with cardboard.
Coffee tin
I'm new to this but the devil is in the details. I've already seen videos talking about copper gaskets that have foam for perfect contact with the lid. If this is for EMP attack, you better get this right. A lot of people will find out they had a painted rim and everything is fried. I would read everything I could and take notes, which I'm doing. It seem logical that redundancy is exponentially helpful. Also, rubber in between layers sounds good. People in the coast think they are far enough away from an EMP going off in the center of the country. My first guess is that during an attack, they would set off at least 5. One for the center of USA and four more for each border. You got 1 shot so get it right. Also, plan what goes in and think about the interior real estate and form factors of your devises.
What really matters, is knowing how to test it. Also, with an emp attack like you are talking abiut, building a faraday cage should be near the bottom of your to do list. I am making a video about this and what should go in the cage for that kind of an attack right now.
Why does it have to be that particular rubber bucket? Could any rubber buckets,like from the dollar store,work? Thank you.
I never said it had to be the particular rubber bucket I use. Use cardboard to line it if you want. All Im doing is making it really fast and easy to do.
Thank short and sweet and tow the point. Who’s there were more people out there to follow you way.
Great video and thanks for testing your work for us! I’m hearing June. Be ready preppers. The world needs the good guys! God bless!
Thanks for the demonstration. Just subscribed.
This looks like a great idea! Also, are you pleased with those midland walkie-talkies? I’m just completely overwhelmed with what to get in that area. Thanks!
They are okay, but hand held ham radio is the way to go.
So do you have a preference on the handheld ham radios? Extra points if they are friendly to ham radio dummies! Lol! Thank you!
@@evelyny7037 I like my yaesu ft60
do up a couple of these buckets. then put then in sealed jobox. ( construction tool storage chests.).
they come in varied sizes also just a metal truck bed box. but seal it up with the alu tape.
but do not allow the little sealed can touch the skin of the larger storage box. have a 1/4 min thick mat, lining the inside of the larger box.
Like this?

I noticed in the video where you put your radio into the cage, that it was playing “Called To Communion” with Dr. Anders❣️❣️God bless you my brother!
To be honest, I had no idea what was playing. I was just looking for a strong signal. But, God bess you, as well 🙂
This is amazing! Great video
Thankyou
Welcome
I did exactly this mid last year, it works great, than for my big items i went by the Drs advice and turned my gun safe into a faraday cage.
How did you do that?
My Liberty safe does not provide emp protection as it sits.
Thanks for sharing! 🇺🇸
Thank you!
You bet!
Hey great straight to the point video! Question: how big is the tubtrugs rubber bucket?
Everything is under the description.
@@LoneStarPrepping ty
Very cool
Awesome thank you
No problem!
Can you use a plastic bucket inside the metal can instead of a rubber one?
Sure. The idea is to insulate the item you put in from the metal of the can.
Some say that grounding the cage is important by attaching a wire to the outside (handle) and grounding it. If the water feed to you house is metal that would be a good place to ground. Newer houses may have a plastic feed.
Yep, some say that.
VERY GOOD!!
Glad you liked it!
Thank you!!!!!
Can a lining from yoga mats or rubber backed floor mats work i stead of bucket?
Sure. Only thing you are doing is protecting metal contents from touching the metal of the bucket. Some people use cardboard. I just made it easy, fast, and simlple.
Can you put several electronics in the same cage? Also are batteries affected in an emp or solar Flare hit?
Sorry I am completely ignorant about this stuff
Yes, if it fits, you must... well, yes, I think that is fine...
If you're planning long-term storage, remove the batteries. They could go bad and corrode the radio.
If I'm adding batteries do I need to wrap them separately also for batteries I haven't opened the package from the store can I leave them in that package? Thanks and an awesome job helping us get prepared...
I dont believe you even need to protect batteries. If you want them there anyway, I would just leave them in original package...
Very good video.
Thanks for watching!
Thanks 👍. Genius!
You're welcome!
Great idea!
Thanks for watching
Wow awesome! Simple too! New to your channel!

What's the purpose of wrapping in aluminum foil if that doesn't stop the radio signal?
You should not need foil or mylar to protect from emp. You should get about 50db protection without. If you want more protection, you may want a mylar bag as well. Testing with 2 way radio shows how well it protects with mylar or foil because the signal is so strong. If I just put an am radio in without mylar, the signal goes away. This shows enough protection. For more testing info, see my more updated videos, especially the video about protecting solar generator from emp.
They're out of stock on the pails just let you know I'll come back to this channel cause that's a great idea thank you so much
They go out of stock ever so often... then available again... I had a hard time finding another one when I did my video on how to make one for solar generstor.
Shows a couple in stock, just now.
@@LoneStarPrepping I bought one of those solar panels for my golab I bought for emergencies. I didn't know you could make them so I got a portable one but it would be nice to go over to your channel learn how to make them maybe I'm equipped to be able to do that
I think my old Lathe and Plaster 100 year old house is one big Faraday Cage. Wireless U-Verse would not reach the rooms. Everything had to be wired.
I have been told that you can use an old microwave for faraday cage as well. Do you think you could do a test on that and show us if that really works?
I heard they work as well. Just put a radio in it that has a strong AM signal. If you can't hear the signal, I think it should work fine.
I did this except used 31 gal Behrens aluminum trash can from Lowe's, taped up the lining on the insides with aluminum tape like you did with the bucket in this video and placed a 20 gal plastic trash in the 31 gal can. I placed one baofeng walkie talkie inside. However when I tested it the walkie talkie was still receiving signal. Any ideas what could be wrong? Thank you
Too strong of a signal... more than you need. Thats why I used foil as well. It was overkill protection. For more info about testing, see my other video. th-cam.com/video/IsPfUxQsoTc/w-d-xo.html
If you can stop a strong am radio signal, that should be enough for standard emp. See link below for my source.
Buy an old large pressure canner at gold will or ask grannies if you can have her old one tape around lid and a ball of foil over steam hole
WAY too much money. It may work, but not practical. Oh, wait... maybe thrift store or something. Give it a try and check back.
Do you need those Specific brands or just the type and materials? Also are batteries uneffected by EMP's? just found your channel after hearing about the report of which you spoke. Thanks for the info and your content. Subscribed for more
Some people use cardboard for liner. Its cheap, but my way is easier and simple. The platic bucket is just to keep metal items from touching the edge of the can. You can also use copper tape if you want. Most standard batteries should be fine. Li-ion batteries may have problems.
I found a 30gal can at Lowes and found a 10gal can at TSC both were same price.
AWESOME!!!
Does the aluminum tape really help in this case? I would think that the adhesive would prevent it from forming an electrical connection to the steel bucket. Can you try another test without the tape? Thanks!
I have tested it without tape and it doesnt work as well. If you put the radio in, even without the lid, there is some shielding. If you put it in with the lid but without tape, there is even less of a signal, for sure. However, when taped up, I get nothing. The tape is what I think gives it just what it needs to reach 50dB shielding. I have a can without tape and just tested it... strong radio signal is very weak but still there.
Also, with tape, my phone cannot be called. I just tested phone and the signal gets through without the can taped up. Im sure different people will get different results, but Its better to be safe than sorry.
I've seen other vids where they connect a copper wire to the cage, then to house grounding rod. Do you recommend this?
Good question...
It may help with lightning protection, but Im not sure. As far as an emp, I dont believe its needed.
I see this works for smaller items but what should I use for my bluetti ?
Look for my video on how to make one for a portable power station.
I’m wondering why it is necessary to wrap the radio in foil and if phones would also need to be wrapped in foil before putting in the bucket?
Read under the descripion for more info on this. This is to give more protection than needed for highly sensitive devices, "just in case". Just put an am radio in the cage with a strong signal to test it. If the signal goes away, the cage should be providing enough protection. See my source under the description.
Why did you wrap the receiving radio in foil before placing it in the can? If the can makes an effective shield, that shouldn't be at all necessary. I like the idea of the 6 gallon can, I figured the old style galvanized trash cans were the only option but they take up a lot of storage space.
Read what I wrote under description. Thanks...
just what I wanted to know....simple/effective.
Glad I could help.
What size rubber bucket fits inside the Behrens? I like your idea for making an easy faraday bucket.
Linda Gonzales
Info on rubber bucket under description.
cool
I just purchased these items and made per the instructions, I don't have two-way radios but I tested leaving my portable Wi-Fi jetpack on and my phone Wi-Fi on I put the Wi-Fi pack in the can and put the lid on and still had a very strong signal, the only way the signal was then blocked was if I wrapped the Wi-Fi pack in foil. Not sure the can is doing much even sealed with aluminum tape? I even tested signal with the can lid off but left the foil wrapped around the jetpack inside the bucket and I still did not get a signal. So seems that the aluminum foil is the true barrier ... would be great to hear your thoughts and if these ideas have evolved over the last few years? Thanks so much
Put an am radio in with a strong signal. If it goes away, you should be fine. Look at my video about how to make these for solar generators. I explain testing a little better.
@@LoneStarPrepping thank you so much for the reply I will do that. I've been watching some of your other videos today, all very interesting and useful. Thanks again.
GREAY VIDEO!!!
Thanks!!
What is the rubber liner for? Does it protect electronics or just provide a bit of cushion?
Keeps the metal from my whatever from touching the sides of the faraday cage.
This is a good test for extremely low power RF Energy, but try placing that bucket near 2000 watts, if its not ground the items inside will fail. You can do this test on your own with a microwave oven large enough to fit the bucket it.
Smaller Nuclear type EMPs create 20,000 Kv/m +++.
The bucket & liner together can dissipate initially, but without somewhere to dump the energy it will fail.
Hope this is helpful Take Care. I have been. Enjoying your solar videos a lot.
shadesV1
Probably the easiest way would be to attach (bolt to bucket) a ground wire where the handle is connected to the bucket & run it to a near by ground rod.
How can aluminum block frequencies when it's used to help frequencies as a antenna?
I have link under video that takes you to an expert on this...
@PreppingOver50 - I'm late coming into your video, but I'm wondering if ESD bags (the smoke or Mylar types that completely prevent static discharge, not the pink bags that only prevent a charge from building up), could replace the aluminum wrap?
It would be interesting to duplicate this test with a cell phone to see if you could call in?
If the can is sealed well enough, it should provide enough protrction. Look at my video about making a faraday cage for solar generator. I dont use aluminum foil. I use emp bags for even more protection if I feel I want it. I buy them from. disasterpreparer.com/product/emp-bags/
Also, a cell phone is not the best way to test the faraday cage.
@@LoneStarPrepping Thank you for the reference to Dr. Bradley's channel. I actually already subscribed to his and watched many of his videos already. Must be why yours are showing on my suggested. Great production. As a senior electronics tech myself, I can authoritatively state that between the two of you, are making an outstanding contribution to the prepper community. Thank you sir.
@@OnHoldAt50 Thank you
Instead of a plastic bucket insert (or cardboard liner) you should have all of your equipment inside a quality waterproof bag placed inside the can. That assembly will serve the same function as the plastic bucket, and provide flood protection.
Next, you should have all of your equipment inside a quality Faraday bag placed inside the waterproof bag. That will provide more EMF protection beyond what the well-sealed metal trash can provides.
I dont want to take the time to put everything in 2 bags and then remove an item to use for a bit, and then put back in 2 bags and then the can. This would be a complete waist of time for me. My idea makes it simple. I am not worried about a flood.
Thank you for sharing this valuable concept, finally looks like some descent cheap and effective way that won't break my bank account!
An EMP attack or Solar storm is something i have only recently started to look into, thank you once again for sharing your knowledge.
An electrician who did some work for me put cardboard inside of my Behrens aluminum cans- cut out a circle for the top and for the bottom and then rolled some cardboard for the inside - what do you think of that?
It will not work if thats all he did. Lots of videos over the years show people using cardboard, but they prepared the bucket properly first. Using cardboard is common.
@@LoneStarPrepping So, if I put the aluminum tape along the seems, THEN the cardboard should work? Or is cardboard no good? BTW, thank you for responding so quickly. Oh, and do I have to wrap the individual items in the foil over and above the aluminum tape and rubber basket. Thanks again
@@truthseeker3967 The only purpose of cardboard, or rubber in my case, is to keep electronics with metal from touching the bucket. A properly taped up bucket should offer enough protection. If you want more protection, wrao sensitive things up in foil or mylar. See my video on how to make a faraday cage for solor generator for more info.
@@LoneStarPrepping Thank you- I have this cookie tins and popcorn tins without any seams that would need taping, that I can see. Are those any good?
@@truthseeker3967 Dont know. Test it.
I would think soldering the seams would be better than the tape. Tape adhesive can fail and release from bucket no?
I agree
@@LoneStarPrepping Quick reply on a 4 year old vid. NICE. 👍😜
@@LoneStarPrepping Been doing some thinking ... have been downloading all free textbooks and stuff that I can get a hold of. Won't do me much good if I don't have a reliable place to store backups and ..... a platform to replay them on if / when everything goes to sh!t.

Hi, would I be able to use both cardboard and chicken wire inside the can for additional shielding? Thank you!
Carboard only keeps metal items from touching the metal can inside. That is what the rubber bucket is for. They offer no emp protection. I would not bother with chicken wire.
@@LoneStarPrepping thanks!
Simple enough
I made something similar, but perhaps a bit simpler/easier. A popcorn tin & plastic bags. Put my phones in the plastic bags, wrapped them good and into the tin. Put the lid back on the popcorn tin. Dialed my number using another cell phone, the phone wrapped in plastic inside the popcorn tin did not receive any signal. To make it even more secure, we shut the phones off, did the above steps, then put the tin inside an old freezer (non-working freezer!) which is inside the barn that has a metal roof. Definitely no signals were received today (10/4).
I used same idea...but stored all my batteries in a BIG christmas cookie tin.
What about not wrapping the radio inside the cage? I would like to get to my radios and other items when I might need them.
As is, the cage should be providing about 50dB based on my testing, which should be enough for an emp. Foil is for more protection, just in case.
@@LoneStarPrepping The foil wrapped radio makes a significant difference, in my opinion
@@MrMotivations the cage provides about 50 dB protection as I have it, which is enough for a standard emp; however, foil would give it a lot more protection...
Ours failed the am radio test. 10 gal behrens can, seams lined w aluminum tape. Cardboard bottom. Any ideas on what we are doing wrong?
If all seams are sealed, including where the handle is on the lid and sides of bucket... everything sealed from the inside, the only thing I think it could be is the seal on the lid to the bucket. Put some alunimum tape on the edge of the bucket where the lid goes. Make sure that lid is perfectly sealed and it should work. The cardboard seals nothing, so be sure to seal the bottom edge of the bucket from the inside.
I did mine with the Behrens Galvanized Bucket 6 gallon and the RECYCLED TUBTRUG 3.5 GALLON, taped up every edge twice over and my cell phone still ran when i called it. However, if I place it in a freezer Ziploc bag and wrapped it with aluminum foil, it stops the signal, without putting it in the bucket. Did I miss a step?
That testing is overkill. Just put an am radio in it with strong signal. If it goes away, then you are getting at leasts 50db shielding, which is enough.
@@LoneStarPrepping Thank You.
How effective is it without the foil since it's already supposed to be going in an effective faraday cage?
Read under my description. Ive updated info on this... also I have another video showing hot to make faraday cages for solar generators... lots more updated info there.
Hey,if i make this cage for my laptops and phones or any other devices would it protect them from something big like emp bomb?
I dont know. Im hoping it protects my stuff. I dont think anyone knows for sure. I did this after researching, and I think it stands a better shot of protecting my things than if I do nothing.
I tested my phone in my completed cage bucket with all seams wrapped with aluminum foil tape, and it did not prevent my phone from receiving a call.😡
I bet it didn't prevent phone from ringing😡
Now, try testing it the way I did, with a radio. Also see my other videos on faraday cages. More info about testing.
How do you know beforehand to put you devises in the can?
You don't. You store them there and if needed, use them and put them back.
I followed what you did, but when I put a cell phone in bucket and closed the lid, then dialed that phone from another cell phone it rang….so what did I do wrong? I then tried putting cell phone in a ziplock baggy and wrapping it with aluminim foil and only then phone did not ring. Why?
What you did wrong was used a cell phone. Please read under the description of the video. Use a strong am radio signal. If it goes away, you have at least 50dB shielding, which is enough. Foil around things just add another layer of protection, about another 50dB, for "just in case" protection. Cell phone has too strong of a signal. It is over testing.
Should I utilize copper wire in creating one of these? The design seems too simplistic, I want to make sure that there's absolutely no way that an EMP is getting in
You mean to seal the lid? If you watch my other videos about faraday cages, I have more info?
Do you need to ground it? Thanks for your channel!
No.
Would a metal filing cabinet also work here?
As long as you can seal every single crack or hole, which I think would be hard to do...
I would like to see how he seals every single crack or gap between every drawer etc... and have it still be useful. I have my doubts. Did he test it?
Thats not a metal filing cabinet. That being said, it seems like an interesting idea. I still see it as higher maintenance cage because the tape will rip at some point and a little large for what I would need as my space is limited.
