Measurement result of shielding effectiveness
The shielding material SR-Shield RS1 presents its extreme high shielding effectiveness to linear, vertical and horizontal polarization and to circular polarized waves.

Communication service SR-Shield RS1
C-network, TETRA, 450 MHz 71 dB
D-network, 900 MHz 70 dB
E-network, 1800 MHz 68 dB
Blue-Tooth, 2450 MHz 67 dB
4 GHz 67 dB

Measurement result of surface resistance and conductivity
The specific surface resistance of "massive" silver is about 62x 104 S/cm (copper 58x 104 S/cm). The measurement result depend on the coating material, thickness and density of the threads, the thickness of the coating and potentially contact resistances of the surface.


The following results were measured:

SR-Shield RS1
Surface Resistance 51 - 62 mΩ
Surface Conductivity 16 - 19 S
