I don't think that you should try to get a single structure to function as both an RF shielded enclosure and a weather protection system. Shielding a building presents one set of physical constraints, and weather-proofing a shielded enclosure presents a different set of constraints. Unless you had some over-riding importance to combining the capabilities, I think you would be served better by building a good parent structure and placing a good shielded enclosure into it.
Consider the problem of getting a 50-ton battle tank to a desert on the other side of the world. You could build a flying tank, or an amphibious tank, or you could build a big airplane and a good tank.

Thanks, Brian. This sounds like what I am talking about to a degree. The structure would be totally self-supportive and not attached to a building as yours is, but would not be in any parent structure at all [i.e. exposed to the elements. Sure there are code issues as well. This chamber would not be in any building at all - would just be by itself outside.

Mac, I'm not exactly sure what you are asking. Stand-alone or not, a 10 meter chamber takes up a lot of space. We have a 10 meter SAC that is supported by its own steal frame structure, meaning, it is not attached to the building. The supporting structure only adds about 4ft to the length and width. I thought they were all built that way, but maybe not. I can send you pictures if that would be helpful. One constructional consideration which is very nice is having the chamber built in a pit so the GRP is at the same level as that area outside the chamber, and there is room under the GRP for your turntable, power cables, etc. That way you can roll large or heavy equipment into the chamber without using an elevator or have to go up steps. Just my 2 cents. The Other Brian From: [email protected] [mailto:[email protected]] On Behalf Of Elliott Mac-FME001 Sent: Monday, August 05, 2013 10:19 AM To: [email protected] Subject: Standalone EMC Chamber? Hello group, A colleague of mine mentioned that he had seen a "stand-alone" EMI chamber at a test lab. One of the obstacles we have in getting a chamber is the lack of space in our building and he thought this may be a good solution to our dilemma. I am not aware of any chambers that do not require a parent structure. Are any of you aware of any EMC chambers [3 or 10m - preferably 10m] that do not require a parent building and operate "stand-alone"?
