M&D Installation Services
Welcome to M&D Installation Services, the one stop commercial EMC website catering for all your Shielded Enclosure requirements.
M&D Installation Services is a collective body of RF Shielding Engineers with a vast and varied knowledge pool in RF Chamber design, construction and planned maintenance.
We offer an extremely competitive and flexible alternative solution to all the industries scenarios. Whether you are looking to expand or thinking of relocating your current EMC facility, we can offer step-by-step solutions. This would include an initial concept brief, full project management, product support and technical backup.
RF Chambers come in all shapes and sizes and so do the companies who own them. At M&D Installation Services we recognise that regardless of a companies size or requirements it is essential to arrive at a cost effective solution which is achieved in an agreed timescale and within budget.
HYB-NF Hybrid absorber
The HYB- NF Hybrid Absorber, the most recent product development in this field, now available. It is a state of the art non-flammable, self-extinguishing hybrid absorber, manufactured from a fibrous composite material, impedance matched for installation over ferrite absorber tiles. The ferrite tile/ hybrid combination provides absorption for broadband testing over the frequency range 26 MHz to 40 GHz.
This new absorber has many advantages over conventional foam based hybrid absorbers.
Reflectivity for HYB-NF-12 when applied to Ferrite Tiles environment
| 30 MHz | 100 MHz | 300 MHz | 1 GHz | 3 GHz | 5 GHz | 10 GHz | 18 GHz | 40 GHz |
| -15 dB | -23 dB | -25 dB | -22 dB | -24 dB | -25 dB | -19 dB | -29 dB | -35 dB |
Ferrite absorber is produced as tiles of size 100 mm x 100 mm and thickness. They re available between 5.5 mm to 6.7 mm. For ease of installation the ferrite tiles are factory glued to wood or steel panels of size 300 mm x 300 mm or 300 mm x 600 mm. When installed in a modular shielded room these panels are screwed directly to the shielding panels. Ferrite absorbers provide high performance at low frequency providing excellent absorption from 30 MHz to 1 GHz. They are very thin allowing chambers to be designed smaller than those previously designed using conventional pyramidal absorber. This can be important where available space within buildings is limited.
