RF-Shielding & Steel Structure
The RF-shielding is Frankonia’s basic system and follows the principles of the Faraday cage. The modular and prefabricated high-quality RF-shielding is typically a pan-type shielding made of 2,0 mm galvanized steel that is manufactured to perfection. Frankonia’s shielding is used for all kinds of chambers and shielded rooms, such as control rooms, amplifier rooms, or any other room that requires a shielded standard.
Shielding attenuation according to EN 50147-1
|10 kHz||≥ 80 dB||Magnetic|
|100 kHz||≥ 100 dB||Magnetic|
|1 MHz||≥ 100 dB||Magnetic|
|100 MHz||≥ 110 dB||Plane wave|
|400 MHz||≥ 110 dB||Plane wave|
|1 GHz||≥ 110 dB||Plane wave|
|18 GHz||≥ 90 dB||Microwave|
|40 GHz||≥ 90 dB||Microwave|
For static purposes, larger chambers require an additional steel structure support that perfectly meets the shielding fixation, considers a variable static design for different chamber sizes and configurations, and adapts to any specific building characteristics and A/C layouts. Frankonia’s steel structure is a totally self-supporting system and does not require a connection to the existing building. Furthermore, for corrosion prevention the steel structure is coated by default akin to RAL 3020 with a guarantee of 10 years. Moreover, Frankonia’s steel structure considers country-specific seismic conditions as well as low point loading to the concrete slab of the building.
