Hello All I have an opportunity to do some extra work on my new ham room that will be in a large cement floor shop building well away from my home and neighbors. I am wondering if anyone has gone to
Unless you're planning to have all your antennas inside the screen room I don't see how you would gain anything in the way of noise reduction. Dave AB7E I have an opportunity to do some extra work on

Chris, a Faraday cage can be a wonderful thing if you don't introduce noise via the penetrations you must have to get signals in and out of the enclosure. Patrick NJ5G I have an opportunity to do som
We built a Faraday cage big enough for an engineer and equipment and learned that a special screen material is needed. Regular copper screening has lots of crossovers that aren't really connected or
Exactly right. Noise is picked up by our ANTENNAS, not on wiring inside our shacks. A shack inside a screen room would be a total waste of a lot of money. As others have noted, what matters is proper

It may be worth noting that some sheet rock (plaster board), ceiling panels, and insulation (foam board) have metallic backing which increase the difficulty of electromagnetic ingress or egress. Scre
Chris, A true screen room must have all cables in and out, including power, grounded to the screen and filtered if not coax. A screen room is needed for working on sensitive equipment when it is unsh

When I was a tech my desk was in a double wall commercial screen room. The screen was Copper. The door shut into a frame lined with heavy finger stock. The door latched using a cam. Commercial screen
Commercial screen rooms do use copper screen. Indeed - http://www.ets-lindgren.com/iDEI-Screen I wonder, though, what the attenuation of that is vs the solid panels. Screen - double layer electricall

It was a double wall screen room With 5W HTs a foot apart, one inside, one outside, caming the door shut took them from overload to being undetectable. At the time (before I quit and went to college)
Having worked in screen rooms, I can say that it doesn't take much of an opening whether it is a door or a slot opening between the walls to allow leakage of stray signals from the AM band. If I were
