Shielded Room

Modular and Prefabricated Standard



Frequency range

EN 50147-1
(IEEE Std 299 optional)


10 kHz to 18/40 GHz

Frankonia shielded rooms and anechoic chambers are designed based on a modular construction system. Prefabricated high quality shielding panels guarantee a maximum of flexibility regarding possible dimensions. All PAN type modules allow for easy handling and entry via standard building doors. The standard modules are bolted from inside every 75,0 mm with high conductivity mesh gasket inserted for sealing the joints of the panels. This facilitates an installation close to the walls of the parent building. The small screwing distance and the precise tightening of the screws with predefined torque guarantee long life shielding attenuation characteristics.
