Subject: Frequency coverage and cost
The web site documents list attenuation only up to 2000 MHz.
Are the coatings usable at 2.5 and 5.8 GHz ?
Please provide an approximate cost in small quantities sufficient to
coat a single 20x20x10' room, or a 100x300x30' warehouse.
Do you have a transparent solution for windows?
I got a reply from sales that they had forwarded my request to their technical department and one of their engineers would reply. -
Regarding the emsec coating:
I have engineering samples of RF absorbent material up to 1/2" thick from other companies. It doesn't have the 60-70 dB attenuation listed for this emsec coating, one type of which is only 6 mil dry film thickness.
Although it is just speculation on my part, I would think to get attenuation this good, the coating has to be very RF opaque/reflective. I don't know what that would do to systems operating inside, but I expect the multipath would be pretty bad.
