you can get and EMP shield and skip all o the sol-ark branding margin
EMP Shield is a bit of a scam.. its nothing but an over priced surge protector that is about equal to a Siemens FS140.
EMP Shield claims that it will protect your equipment from an electromagnetic pulse, but that's only 50% true.. the other 50%, which they won't admit to, is a total lie.
Pretty much the only EMP we're concerned with for this discussion is a high altitude nuclear attack.. When that happens, the electromagnetic pulse comes in two flavors: 1) Conductive and 2) Radiative.
I have little doubt the EMP Shield product could stop the conductive pulse.. I'm sure it would probably do a fine job, as would some other surge protectors like the Siemens FS140 for only $180.
The problem is that there is no way for the EMP Shield to stop the radiative component.. at least not without breaking the laws of physics. The radiative part of the EMP pulse will directly couple into your home's wiring and your electronics.. and there's nothing that even the best and fastest surge protector can do about that.
Is Sol-Ark insulated from an EMP? Well, they say it is.. and we can make two observations about that.. 1) protection against the conductive component isn't difficult, and 2) protection against the radiative component will require a conductive Faraday cage.. IE: A metal container.. which I believe the Sol-Ark is a metal box.
But the real question about Sol-Ark's EMP protection is "how much protection?" Faraday cages are NOT like condoms or seat belts.. its not an ON or OFF thing.. Faraday cages are more like safes.. the better the safe, the harder it is to break into. How much attenuation does it's metal case provide with all those holes, buttons, and display's ? You need 40db for a standard nuclear weapon.. but you'll need about 60db or more for a super EMP weapon.. and making a super EMP weapon isn't hard to do.. you just replace the neutron reflector, called a tamper, with something less reflective..
That said, I'd be very surprised if the Sol-Ark could survive the electromagnetic hot-spot of a high altitude nuclear attack.. It might survive the middle or edges of the radiative pulse, but I'm skeptical of a direct hit.
My electronics are stored behind two layers (steel - aluminum) and that provides about 75db of attenuation.. My super sensitive electronics like the HAM radios, computers, etc, are stored behind 3 and 4 layers (steel-aluminum-aluminum), and that provides about 120db.. Nothing is getting through that..
