Shielding test results

EMF Shielded Garden Canopy Material Shielding Level


This measurement of the screening attenuation of electromagnetic waves from 30 MHz to 18 GHz was carried out in conformity with standard ASTM D4935-10.



Measurements were to ASTM D4935-10, IEEE Std 299- 2006, IEEEE Std 1128-1998, ASTM A698/A698M-07, etc. at our manufacturing facility. For quality managment purposes each batch is measured separately.


Measurement System

Measurements are carried out using a professional vector network analyzer Rohde & Schwarz ZNB20 with 140 dB dynamic range up to 20 GHz.

The antenna for ASTM D4935-10 are modified TEM-cells, that can measure even small samples down to 30 MHz in the far field. The samples are measured with radial polarisation (all directions, not only horizontal or vertical only), which matches typical forms of environemental exposure. All electrically conductive and thin samples can be measured perfectly with these cells.


Silver SuperShield

1) Silver SuperShield material gains a tarnish over time. Often the fabric has areas of staining right from the start, this is a natural result of the manufacturing process.
If you do not wish to accept stainings or discoloration, please choose canopies made from Swiss-Shield®.
2) Silver fabrics have a limited durability, which depends on the frequency of movement. 
3) Our silver fabrics don't contain nano-silver, but a thick pure metallic silver layer.


This product is made to special order only. Please allow 14 working days for delivery from receipt of order.  
The product does not include the umbrella which holds it up or the weighted hose line which holds the canopy on the ground. The umbrella needs to be 3m in diameter and the weighted hose line needs to be 10m in length.
