  • ETS-Lindgren's Series 81 Radio Frequency Shielded Enclosure uses a time-proven design for superior RF Shielding and EMI Shielding applications, with more than 10,000 installations worldwide. Read a case study on how this product was used for drone/UAV (Unmanned Aerial Vehicle) testing.

    These EMI/EMC shielded enclosures have modular panels can be built to almost any dimensional configuration. Thirty-six standard formations are available, or we can custom design a configuration that best fits your needs, including solutions with unique geometeries, RF doors, filters, penetrations, and integrated waveguide air vents.

    In the heart of the RF shielding system are the 1.9 cm (.75 in) thick dimensionally-stable cores, laminated with 28-gauge sheet steel on both sides (cores meet ANSI A208.1 specifications). The steel laminate provides the excellent attenuation to magnetic and electric fields and plane waves.

    Panels are joined together with a 3.175 mm (.125 in) "hat & flat" clamping system. No special tools are required for construction. Enclosures can be erected, dismantled, and moved to another location as needed. Enclosures are self-standing and do not require attachment to the parent building.
