RF/EMI Shielded Modular Enclosures

Select Fabricators patented RF/EMI Shielded Modular design allows a lightweight, expandable, high attenuation RF/EMI Shielded Enclosure at any dimension.

Select Fabricators’ RF/EMI Shielded Modular Enclosures offer a semi-permanent or permanent system that provides over -85 dB attenuation over the range of 20 MHz to 18 GHz (IEEE® 299) and requires no additional weight reinforcement for a fraction of the cost of a hard-wall chamber.

A large-scale RF shielded enclosure for shielding/isolating RF/EMI for MIL-STD-461 or other EMC Testing. The Modular RF/EMI Shielded Enclosure can be scaled to shield warehouse, lab, or garage areas for testing larger products where a portable size will not comply.

When RF/EMI shielding and testing is required for large aerospace, satellite, automotive, and defense products a standard anechoic or shielded room may not be able to sufficiently handle your team’s shielding needs.

Select Fabricators’ patented Modular Enclosures (US Pat No. 9,930,816 B2) allow customers to customize a design with the following advantages:

  • Unlimited sizing at any dimension
  • Quick lead times compared to similar sized hard-wall structures
  • 1-2 week installation
  • Semi-permanent structure allows flexibility for future uses of the work
  • Lower in cost and weight than a permanent welded shielded chamber
    • 10:1 weight ratio to a welded screen room
  • Modular design allows future expansion of enclosure’s height or length/width
General Specifications
  • Over -85 dB attenuation over the range of 20MHz to 18 GHz (IEEE® 299)
  • Constructed with Nova Select™ acrylic coated Ag/Cu/Ni conductive fabric.
  • Patented Design: Pat. No. 9,930,816
  • All modular enclosures are made in the USA
