A short excerpt from: http://www.urbansurvival.com concerning EMP and links for protective information-

Radio Time

On Steve Quayle's show tonight at 6 PM Central - 7 Eastern. Talking about (among other things) the EMP series which I did for Peoplenomics. Speaking of which, a letter worth sharing as feedback for non-subscribers:

"Thanks for your recent informative subscriber site article on EMP protection. As a former USAF communications officer, I can attest that EMP is a serious concern and all branches of the military have protected equipment.

Below is the URL for a good site in re Faraday cages for protection from EMP events. The easiest ones to make/use are to stick your small electronics (cell phone, radio, laptop, etc) into a grounded microwave oven, or to use a grounded space blanket to cover a cardboard box into which you can place your computer, TV, etc. In an emergency time constrained situation a grounded space blanket can also be thrown over your electronic equipment.

Small mesh chicken wire can be used to line a small room, a garage for your car, or a small common steel garden shed can be grounded and used to store spare/emergency electronic equipment.

Faraday cages can be built to totally enclose sensitive equipment NOT in use. Exposed radios, computers, and similar equipment are almost impossible to protect if they are plugged into a 110 volt household electric circuit. If the Faraday cages are sitting on a conductive surface, they should be grounded. Grounding is safer in any case, though.

If items inside a metal shed need to be grounded, the ground wire should be insulated and go to a separate ground rod to prevent feedback!

Ground rods should be driven down to wet earth, if at all possible, to provide a sufficient ground. That may mean an 8 foot ground rod, or even longer, depending upon your location.

As I told subscribers last week: EMP looks like it's in the same pot with terrorism prior to 9/11. A lot of talk, little action, and very, very little public awareness.

IF an EMP occurs, Your Cell phones would be rendered useless anyhow, only reliable form of communications after a post EMP scenario would be HF with an NVIS setup for long distance communications. You can use anything between 3-30Mhz for long to short distance communications.

I would not consider an EMP burst as a high threat scenario. Odds are greater that a natural disaster would disrupt your lines of communications or a few well placed conventional explosives at key sites that provide communications support/services. And they can render Cell Phones, Standard Repeater or trunked based VHF/UHF communications useless (ie police,firefighters etc..)

What's the best way to ground a metal box that is sitting on a wooden shelf or on glass?
