  • High screening attenuation for a cotton fabric
  • Excellent cost/performance ratio
  • Textile characteristics: Washable, easy to iron and process
  • Quality grade: Very high
Order quantity: This product is cut off according to your specifications, a return or revocation are not possible.
Screening attenuation: All stated attenuation values apply at 1 Ghz. Measurement to ASTM D4935-10 or IEEE Std 299-2006 or IEEEE Std 1128-1998 or ASTM A698/A698M-07. You find the test report above under "Report screening attenuation".
Grounding: Not electrically conductive. No shielding of electric fields (LF), these must be reduced by additional procedures. We recommend the shielding with NSF34, NCV95 or the decoupling with a demand switch.
