​​​The Series 71 Copper Screen Room is designed to provide a radio-silent environment to perform electronic product development and trouble-shooting, as well as conducted emissions and radiated emissions EMC testing. 

With 32 standard sizes to choose from, the ETS-Lindgren Series 71 Copper Screen Room can be utilized in almost any type of manufacturing or testing environment. The design consists of a double-layer of 55.9 cm x 55.9 cm x .04 cm (22 in x 22 in x .015 in) copper screen with steel framing and steel-clad structural panels. The room provides excellent attenuation to magnetic fields, electric fields and plane wave

Key Product Information


The Series 71 features a double layer of 55.9 cm x 55.9 cm x .04 cm (22 in x 22 in x .015 in) copper screen mesh weave to deliver excellent attenuation levels on the upper half of the wall panels. The lower half of the walls, floors and ceiling panels are constructed using our standard Series 81 panel construction.

Copper is highly recommended for use in shielded screen rooms due to its conductivity and oxidation properties. At the same time, a copper screen mesh affords “hear-through, see-through” advantages.



The Series 71 Copper Screen Room shares a clamping system common to that of the Series 81 design. The upper panel section of the room's walls have a double layer of copper screen mesh. The Series 71 Screen Room allows for easy visual and audible communication through the upper panel section and eliminates a sense of confinement that may occur in solid shielded rooms. 

Series 71 Copper Screen Rooms are highly recommended for testing applications below 3 GHz for wireless product testing and communications devices.

In the Series 71 Screen Room, the lower wall sections are manufactured using solid galvanized steel structural panel sections for long-term durability. Panels are joined together with an extruded “hat and flat” and “cove” clamping system to provide uniform and consistent pressure contact against the shielded panel mating surfaces. These structural clamping sections are zinc-plated to resist corrosion and are joined with self-taping zinc-plated fasteners spaced four inches on center to ensure a secure shield. The corners of the shielded room are secured with precision-machined trihedral end cap sections. The Series 71 incorporates of copper screen mesh sections on the upper half of the enclosure to allow communication through the screen.
