Thank you both. Use of ground rods (with heavy cables) is good advice for diverting strong waves through common frames.
Steel wire mesh/screen (for those of us who can’t afford copper or gold mesh) insulated from both the outer case and the object to be secured can add an extra layer. It can also be used around insulating seals (better if completely around the case with lid seals). Even aluminum foil, though it’s not the greatest conductor, insulated on both sides, may help a little as an extra layer for small items.
RF waves are a little different in some ways from surges through lines, in that the tighter and more conductively continuous the case, the more secure against RF waves (only guessing from compliance with FCC rules in past computer integration).
Yes. In further considering a little knowledge about RF pulses, it might be important to seal (with steel or at least tightly with aluminum) holes and gaps in the body of a vehicle. An RF pulse is a bit of a different animal in some ways than a line spike. Think of sealing your vehicle body from radio signals with a very wide band. ...similar in effect. If you can’t contact anyone from a cellphone or personal, two-way FM radio from under the closed hood of the vehicle, it’s probably pretty well done. ;-)
...different animal in some ways from a line spike, even. Little grammar there. ;-)
The whole muslim world needs a titanic slapdown to stop 1,400 year of their insane aggression. If nuking Mecca and its despicable Kaaba to a smoking radioactive crater would destroy their faith in a false powerless god, it would be worthwhile to do.
FYI, a suggested method for shielding a garage-parked car is the good ole’ SPACE BLANKET with a functional grounding strap added. In other words, cover your vehicle with an aluminized mylar sheet, well-grounded to earth.
I was told that the pulse is quite directional (not sure I believe that) and thus draping your car is good enough - meaning you don’t have to wrap the vehicle.
AND ... Bass Pro Shop 2-way radios in a small gift box wrapped in foil (the gift box wrapped) inside a shoe box wrapped in foil and set on metal shelving resting on a concrete slab OUGHT to be good enough to save the radios.
LASTLY - put larger items in metal trash cans, ground the cans, tape the lid on and you’re good to go as well.
No need for Mil-spec Farraday cages or Tempest shielding.
so I hear anyways ...
Great idea. Remove the guts, ground the chassis. Contents in the plastic cooking cavity are shielded from the conductive frame. Clever.
And I read that you need to disconnect the car battery while stored. I guess to keep it from being ‘blown’ by the pulse? Not sure I believe that, but I am not a EE either!
Interesting reading.
Analogous to “One Second After”
Part fiction story, part "what if", part survival manual.
hmmm. the “Lights Out” author needs a better, more proactive publisher to get the title in print, and available via Amazon. ;-)
Oh, and the combat engineer Army specialty was more of an unrelated civil destruction thing (boom). ...not much electronics knowledge involved and no real engineering.
Well...maybe not very civil. ;-)
