RF Shielded enclosures, Radio Frequency Shielding

for EMP ,EMC E.E.G., E.M.G. and E.C.G. equipment from external RF emitters or

RF emissions from similar equipment within hospitals, laboratories ,startup company and military companies .

 RFI room create an RF isolated environment  (faraday cages, shielded chamber )

An RFI room is a room that attenuates Electromagnetic signals 10KHz to 40GHz ).
This attenuation allows operating a electronic equipments inside the RFI room in a way that will not interfere with the operation of external to any  networks

Dolev can provide solution to EM Emanations and their control at a facility level, and provide installing
and testing a shielded enclosure in a facility.

The RF shielded enclosure meets the requirements for electromagnetic attenuation through tests conducted by a third party following test methods: EN 50147-1, NSA 65-6, or IEEE 299. MIL-STD-461
