Select-A-Shield RF EMI Shielded Tabletop Enclosure Boxes

Select-A-Shield tabletop enclosures are used in pre-compliance testing, secure communications, mobile device/computer forensic investigations as well as temporary EMI shielding.

Shielding Effectivenss, Double Layer Tent with Internal Vestibule Shielding Effectiveness of a walk-in RFI EMI shielding tent

Referring to the chart above, Select-A-Shield walk-in enclosures have achieved  a minimum of -85.7 decibels of shielding effectiveness in the range of 400 MHz to 18 GHz and a minimum of -96.9 decibels of shielding effectiveness in the range of 1 GHz. Shielding performance data must be carefully scrutinized to assure the enclosure will meet the requirements for a specific application. Select Fabricators used the IEEE® 299 standard test, conducted by an independent test lab on a complete assembled system including installed components operating under typical conditions at various frequencies measured through the tent wall at multiple locations in the tent. The minimum readings indicate shielding functionality that can be expected in use.
