Solid Wall
Refurbished RF Shielded Rooms
Modular Enclosures to Size Required

The CIR shielded rooms will provide up to 100db min. of attenuation from 14 KHz to 10 GHz when subject to electric fields and plane waves.
We specialize in shielded enclosure manufacturing, modification, refurbishment, installation, and RF testing. CIR manufactures and installs steel clad, clamp together, shielded enclosures. We recommend the steel clad system because, with its sturdy construction, it is easily modified.
Enclosures
We are always looking for good used RF shielded doors. If you have any Universal, RayProof, Braden, ETS-Lindgren (knife edge) doors to sell. Please send us an email. |

Shielding effectiveness values are expressed in logarithmic, not linear, terms. Therefore, 80 dB of shielding effectiveness is not double the 40 dB level, but 100 times greater. Another way to express effectiveness is attenuation ratio, which compares the attenuation signal strength outside and inside the shield as shown below. |
