Budget Radio Frequecy Curtain

alinepapille
Just came acrosse a budget radio frequency curtain at blockemf.com

http://www.blockemf.com/catalog/product_info.php?products_id=5072

Sounds too good to be true as it is a fraction of the price of most
shielding material.

Has anyone tried this? Is it worth trying?

Thanks,
Aline

LOOKS LIKE SURVIVAL BLANKET MATERIAL - HOW LARGE IS IT ?

I bought one. It is a good buy. Aluminum foil is probably much more
effective, but
this is nice because it's bigger and very lightweight. It's probably great
if the signal
you're shielding is weak or if it's for a hallway or somewhere you won't be
spending hours
every day.

I bought some of them with a grounding cord but in the lessemf.com site.
I don't know if is the same curtain but at less the description is
very similar. In the lessemf claim that the attenuation is 20dB
and in the blockemf 40dB,...

http://www.lessemf.com/plastic.html

I used it to shield wireless that comes from the next room and
attenuates greatly the radiation. I used the electrosmog detector MW1
to check it. I think that I need another layer of this material
because I hear a small wireless sound yet and I know that the
sensitivity of MW1 is around 0.03- 0.05 V/m.

I have also a digital meter but I don't remember exactly the amount of
radiation that was before and after the shielding
(I'm thinking that went from 0.3V/m to 0.03V/m but I'm not totally
sure), and at this moment
I cannot measure it because they are not using wifi.
Maybe if I detect that is active I can send you my digital measurements.

Re: Budget Radio Frequecy Curtain

For microwaves there's little point in grounding it (but it could be safer
in
terms of if it gets into a live outlet).

BlockEMF says "40dB(100:1)". 100:1 is 20dB, so LessEMF's figure is probably
the one to look at.

I could believe it is 20 dB in terms of power, which means just 10 dB in
terms of field strength.

it looks to me like its made of the same material as 'survival
blankets' that runners, mountaineers, etc use, that i've been using to
help screen out RF radiation at my mum's when i visit. i've always
been impressed with its screening abilities compared to tin foil, but
think the plastic bit does something weird, not sure what. Would love
to know what the metal is they use....

It is aluminum.
