I am trying to design an RF shield or farady cage to as a project.
The Idea is to put the wireless handset inside of the cage.
The cage will block and thus interupt the signal from the Handset to
the base. Is this possible.
Any website I can go to to find how I can build such a cage?
I've ask this on another group..
uh no.. microwave ovens dont work.
I tinfoiled a carboard box and earth grounded it... didn't work.
I grounded the HS to the shiled itself, and it dropped a bar. Didn't
work well.
where am I screwing up?
If I remember correctly it also depends on the thickness. The thickness
will only block out wavelenths that are smaller. (sorta like sound waves).
So while the tinfoil might be thick enough it might not be doing as good a
job as something thicker.
Another issue, I think, is one of smoothness. Atleast in HV apps you want a
smooth surface because the electric field is much stronger at sharp points.
While probably not significant in this application it might have some
effect. I know they use wire mesh but this is pretty smooth compared to tin
foil(atleast how it always turns out).
Not that these are necessarily significant(or even true) for your problem
but they might be worth investigating farther.
