Specialized RF Shielded Enclosures Cope With ...

... vehicle exhaust, outdoor environments, fire hazards, and work

center testing applications.

Flexible, portable, high attenuation EM RF shielded environments are in demand for many testing applications. Vehicles of all sizes, can be tested in a RFI / EMI screen rooms with proper intake and exhaust systems. Mobile outdoor RF isolation testing tents can be assembled on-site when needed in isolated areas. Fire retardant liners and systems support local fire code requirements. Work center structures assist semi-conductor manufacturing. Vehicle Enclosures Vehicles from small garden tractors to large aerospace units (Mil-STD 461) can be set up for testing in a modular unit with collapsible sections, removable thresholds and/or custom-sized doors. A new, removable threshold is now available that eases entry into a patented single door, double magnet system (US Pat. No. 9,029,714) including level grade guides and recommended floor protection mats. The door itself is optionally removable as well as sized for the vehicle. A recent example of this design is a 20’ x 18’ vehicle door to accommodate the object under test. Shielded intake and exhaust systems have been developed to deal with vehicle emissions. The systems feature large vents with an exhaust waveguide vent pipe. With proper design and preparation, vehicles of all types and designs can be tested in-house or outdoors, see below, in mobile, modular units.
