Portable RF/EMI Shielded Enclosures Select Fabricators’ RF/EMI Shielded Portable Enclosures allow easy set up and break down for quick deployment when and where the enclosure is needed. As an affordable alternative to traditional hard wall chambers, SFI’s soft wall enclosures match shielding effectiveness in comparison. Independent testing to IEEE? 299 of a complete assembled tent system including installed components, resulted in a minimum signal attenuation of -85.7 dB over a range of frequencies from 400 MHz to 18 GHz measuring through the wall at multiple locations. Customers can choose from an SFI standard size enclosure or opt to have an enclosure designed and built to custom specifi cations Optimum Protection Manufactured using NovaSelect? RoHS Compliant silver/copper/nickel conductive fabric and utilize single door (US Pat. No. 9,029,714) or double door (US Pat. No. 8,530,756) patented seal system. The double magnet strip closure delivers maximum isolation. Construction Made in the USA, SFI’s RF/EMI Shielding Enclosures’ exterior fabric walls are Nova Select? conductive silver/ copper/nickel RoHS compliant material. This fabric has average shielding effectiveness of -85 dB in the range of 30 MHz to 1 GHz and averages -90 dB in the range of 1 GHz to 11 GHz. (See chart below.)
