The 0 dB step at 6GHz is -2 5dB. Which is to be expected. Then from there it's very close to 1dB per 1dB attention.

I received this device not working properly and tried to get a replacement. I did not receive the replacement package as it was held up somehow in transit. I think Amazon will resolve the issue.
