HNG100 is a compact woven, metalized polyester netting for the protection against high-frequency radiation (HF) and low-frequency electric fields (LF). This professional product with more than 98 dB attenuation is typically used for ministries of defense, banking houses, laboratories, etc. Where competitors advertise with 98 dB, they ignore the fact that the attenuation usually drops to some 80 dB at higher frequencies which is identically to the HNG80 or HNV80. We had HNG100 produced with a very high metal content. With a resistance/square of only 0.01 Ohm and a close mesh-width the HNG100 achieves real 100 dB even at high frequencies.
