It is NOT. ALL ham mics (as well as many pro mics) meet that VERY broad 
description -- it tells us nothing!  To be meaningful, there's must be a +/- 
dB tolerance, AND you need to see a graph of the frequency response. 

To understand ham mics and their frequency response, study pages 41-45 in

Also, study Appendix 6 of
