Canandaigua, NY — Select-A-Shield RF EMI Shielded tents are designed to be used for everything from pre-compliance testing to secure communications. To assure shielding effectiveness during entry and exit, Select Fabricators, Inc. has developed a vestibule for its Select-A-Shield walk-in enclosures. Like most enclosures opening the door of any walk-in enclosure can degrade immediate shielding effectiveness, resulting in possibly compromising data capture or data corruption. With the addition of the Select-A-Shield vestibule, which is integral to the enclosure, the shielding environment is kept intact for consistent shielding performance — something like the airlock on a space vehicle.

In a typical 9 x 12-ft. (2.7 x 3.7m) length Select-A-Shield tent, the vestibule is situated in the right hand front corner. 3 x 4-ft. (0.9 x 1.2m) in size, the vestibule provides entry for personnel via a separate single door double magnet (patent pending) closure system which opens out. The vestibule has its own separate conductive floor, door and inner walls apart from the tent itself which allows maximum isolation for continuous testing or examination. The door opening to the main compartment opens inwards which makes entry and exit easier.
Select-A-Shield RF EMI shielded enclosures with vestibules typically include a white ESD liner and ventilation. According to the company, ventilation is necessary when people occupy an RF EMI shielded tent. The fan and vent system is also RF EMI shielded to preserve the shielding effectiveness of the structure. The white ESD liner not only protects against static, it also helps technicians read and record data against a neutral, brighter background.
The enclosures are constructed with RoHS-compliant, durable, lightweight, Silver/Copper/Nickel, Nova Select fabric — the company's proprietary highly conductive material. Shielding effectiveness for a vestibule measures -73dB with both doors closed at 916MHz. A double wall RF EMI shielding tent with ESD liner yields an average SE of -78dB average from 150kHz to 18GHz without the vestibule.
The company's RF EMI products are suitable for numerous applications including wireless device development and testing, secure communications, satellite communications testing and isolation, EMC pre-compliance, medical and aerospace equipment shielding, cellular and computer forensics and RFID shielding for commercial and industrial settings. Select-A-Shield products can be customized to almost any size and option configuration.
