Would you need to cover it with Aluminum (cooking ) foil ?

Yes, it will make a very good protection, especially if you also cover it with aluminum foil.

Thanks Steven

Your advice is much appreciate

Great thread.

I have an FM transceiver that I keep in a US military ammunition can that I plan to use in a shtf situation. I have read that these make suitable Faraday cages. Would you concur, Steven?

Thanks in advance.

Yes, these metal boxes will make a perfect shield because it's all made of steel. But the paint on it act as an isolator, you don't want it to redirect EMP. Only make sure you file it to remove paint and dirt. Then you connect (weld with tin) the wire earth ground to it. Or buried into the ground.

Thanks for the info Steven.

i believe it is also necessary to insulate the radio from the box, on the inside.

Yea I've been thinking that maybe it would be good to line the box with rubber or some sort of insulator, although most things are in a plastic case so I guess that should do it.

Yes, you don't want your components to be in contact with the shield (they can be in physical contact, but electrically isolated), only the metal framing, not the components.

After reading in another thread about microwave ovens.
I think that if you were to earth one then it should be ok to shield your stuff.
You could use a old one which is not connected to power.
If your in the UK or Oz then it would be earthed if plugged into the mains. In the UK you could just remove the fuse so there is no chance of it turning on and cooking your stuff, and it would still be connected to earth.
Ok it's not going to be very big, but big enough to save your ipod, a radio etc

Anyone know a reason why this would not work well as a Faraday Cage??

I like this idea because it's simple, not costing too much. It won't be as efficient as a Faraday cage, because for this, you will need to cover all the micro-wave with double layered aluminum foils and connect them to the metal casing of the micro-wave. A simple modification that will assure best result.

Thank you for this idea Swanny, Steven

[Swanny]

No probs Steven glad to be of help.
Just talking to a friend who threw away his old microwave yesterday, I could have used that.
Good idea about adding foil to it

Would it be possible to ground the entire house?

I live in a single detacted home and I remember reading somewhere about a 5 feet antenna on the top of your house.....unfortunately there wasn't a lot of info to go on.

Any help is much appreciated.

Thanks and have a great super day!

Salut Julius. Yes, you have read it here in one of my post on this thread.

This is a good idea as long as the transceiver is Insulated from the metal can. Even a simple metal lunchbox or metal cookie/chocolate box is good. Just don't forget the insulation.

Most of the posts in this thread seem highly speculative in nature.

There does not seem to be much definitive information in public, and people who understand RF are few and far between. Bleep! seems to be one of the few that understand.

What worries me, is that people talk about EMP as if it were some kind of constant. EMP's can of course be of varying strengths. The need to protect against EMP caused by a local nuke, is different than the need against one caused by a CME type phenomena, or a high up "big" nuke covering a wide area.

The earlier advice that cars would be unaffected is dodgy since most modern cars are very dependent of digital technogy.

It is true that if people start slinging nukes about, we would have more to worry about.

IMO I see no reason why they would want to EMP us, if tshf they would want us to stay in doors and watch the tv/listen to the radio so they can feed us BS and tell us to be good little people. They can easily turn off the phones and the net to stop us talking to each other.
I still like the idea of protecting your stuff just in case.

The sort of cars that would be ok after a EMP hit would be those that have points, so if your car is about 20 years old and you weren't driving it at the time it mite be ok. An old mini would be good.
Anything with a ECU would be no good.
A diesel engine is very basic and doesnt need electronics to run once it's been started,

Why don't you just delete the thread if it's speculative. I work in this field and yes, antennas does concentrate EMP just like radio wave. Read the first post I made, the reason I brought the topic was about a future EMW of great strength coming from the sun according to Henry Deacon's somewhere in 2009.

Since, I work for a large Electric power company and already have lived this kind of problems, I put some simple advices, not expensive, to protect one electronic devices.

Now, if you don't agree it's ok. But I'm not being speculative, plus I provided some useful links since I can't begin to write a book about the topic on this thread.

And yes, EMW constantly comes from the sun.

Namaste, Steven

[Julius]

Thanks for the responses guys.. I can see that this is no easy topic and depends on what we are defending against.

Let's say it's a "future EMW of great strength coming from the sun according to Henry Deacon's somewhere in 2009.", then I guess the antenna thingy would help.

So if I got this straight, I would put this antenna (every corner) on top of my home...do I run the wires down the side of the house to the ground? (from the antenna), or do I find a metal piece (outside water spout) and attach a wire to it and the other end to the ground?

I also have a scooter, I think that would be safe from a EMW (it's a manual start).

Thanks and sorry for my ignorance.

[Baron Cross]

How about old ovens, refrigerator or freezer would this work with emp?

Ovens, refrig, etc.?? Yes they would work.. especially if you replace the seals with copper braid or similar.

Where did Henry Deacon state the 2009 thing????
Surely he never said anything of the sort.


He may have hinted that a CME could happen.. but that is not a prediction. It was more like an example of another EMP source, wouldn't one think?



There really isn't anything else to say in this thread. We have experts and then we have experts.

Sorry.

I hope this misunderstanding is down to language barriers. First, it wasn't not a "moderator" comment. Secondly, it was not aimed at you though I happen not to agree with the way you have described the function of an antenna in this context. It might not be that you are wrong in your understanding, but the way I have understood your explanation.

I agree that RF prorogation is a complex subject so this is bound to happen. I cant write a book either - or even reference one at this stage. We cannot possibly get this right on the forum without expending huge amounts of time and words.

So please understand that I appreciate your work in this thread. I know (because you told me once before) that English is your third language and it is clearly obvious that this is a lot of work that you have done.

Speculation or not, this thread has managed to get an important message on the record.

On the technology, IMHO Bleep clarified the matter perfectly I have nothing to add either.

Namaste <-- first use on this forum from me, and meant it.

Hi Anchor. No worry. I understand your statement and admit I should have put "antenna" between quote. I was not referring to an emitting antenna, but rather a simple an inexpensive mean to catch and reflect EMP.

I will clarify it. When an EMP hits solid material, one part is absorb and another is reflected. All depending on the angle of the wave, 90 degree reflect the most, and the conductivity of the material. So, in installing antennas to the roof will not absorb and reflect all the wave, but will certainly diminish it's overall effect if it's grounded. I understand one can see it as not important in normal case, but as I said in the OP, it is not about normal condition. Because the ultimate shielding of one's house would be to cover the roof with grounded unpainted metal sheet. But, I didn't want to put it that way, because of the cost and complexity of this.

Lastly, the purpose of the post is to give simple, not costly advice to protect your electronic devices in case of strong EMP coming from the sun.

Here is something well written and totally conform to my experience: http://standeyo.com/News_Files/NBC/EMP.protection.html

To you Bleep! I appreciate your presence here. I am in no way pretending to be expert. And I do not question your statements, they are true and perfectly welcome. About Henry Deacon. I remember it was mention in one interview with Bill and Kerry. I can't remember which one, I have seen them all, but it was Bill who mentioned it to the person interviewed. Maybe someone here may remember which interview it was.

Namaste, Steven

FANTASTIC Thanks so much for sharing

"If you worried about your body, especially your brain since it's an electro-magnetic device, well shield it, lol. I mean you can put antennas on the roof of your house, 1 antenna wire 1/4 inche by 5 feet long, covering a sphere of 20 feet, and protect the entire household. The important is conductivity (metal) and good grounding (deep in earth)."

This will not work and does absolutely nothing for you. The idea of putting antennas on the roof top must have come from the idea of lightning rods. EMP is not like lightning. You cannot 'draw' EMP away from things in the same way as you can with lightning.

Common EMP has little or No effect on your brain.

Also, if you ground something, the ground wiring Must be very short distance from the shielded 'item' to the actual Earth grounding point or the so-called ground wire will act as an antenna instead of as a grounded circuit. Using housewiring grounds in wall sockets is not a good idea and may Not be effective.

Copper foil is a better option if you wish to create a good faraday shield. Aluminum - is ok for shielding the Magnetic component of the Electro-Magnetic pulses and will suffice overall if done properly.

Antennas and any wiring attached to a device should be disconnected for best protection.

On second thought, maybe it is time to go buy some 'wabbit ears' (an old-stlye of TV antenna) and put them on my new hat: http://www.rogue.co.za/html/more_headwear.html

Hi Bleep! You had me open my old books there.

First, I agree that common EMP has little effect. But we are NOT referring to common EMP in this thread. Great magnitude EMP can affect the brain. Here to back my words: http://www.blurtit.com/q642109.html

Here experiments on rats: http://ieeexplore.ieee.org/Xplore/lo...number=1282261

Last, yes copper is a better conductor element, but it is more expensive and does oxide much faster.
