Diamond X510N & X510MH Antenna Teardown, is it a Fake?

Comparison of Diamond Antenna X-510N (200W) Vs Diamond X510MH (330W)

Brought the X510HM new from good a UK supplier, but is it a Fake?
Nothing about The X510MH seems to have the build quality of Diamond X510N.

Did you ever wondered what was inside?
All the measurements were taken on my LCR at 100KHz and 1v.
