Speaking of Faraday cages, how would one go about doing this?
I'm preparing an area of my basement (directly below the breaker
box :) to be used as a computer room, and I'd like to shield it
as much as possible. Since the TV is going to be ~20 feet from
the VAXen, I'm rather concerned...
I'm not sure you will get all that much interference out of one, unless
you run it with the chassis open. There is a G_D awful lot of shielding
already in the chassis, which is built of thick, heavy steel...
The cages I've seen are made from an expensive copper screen,
like window screen, but they are for doing FCC interference
measurements, not shielding. I can get 1/2 inch square fencing
from the look home improvement center, but it is galvanized and
quite a bit coarser...
I doubt that would do too much-- but IANAEE. YMMV. If I were to do
something like that, I would check the local scrapyards for copper screen
(just on the off chance) and most likely use {galvanized,}steel
window-screen. Should be pretty cheap, all things considered.
Comments?
Never hurts to try. Let us know of it works out...
