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.

Thanks for sharing this information

[@andrewcollins3402]

Very informative, thank you!

[@tangraelectricpower8754]

What material are they made of? Is this copper or maybe brass?

[@VicGreenBitcoin]

Why not a SWR measurement indoor?

[@Chris-tx9ou]

how do you crack these open - id like to open up an x50

[@bikemike20]

I have the X700, I am tempted to downgrade back to the 510 as the 700 is just so long! It's fantastic for 2m but 70cm it seems the lobe is too low down

Which is better sir..

Hi, after a few months of pushing 250W via the MICROSET SR-300 300W AMP into the X510-MH it has showed no signs of deterioration from either input power or weathering from autumn high winds and rain. The SWR is a constant 1.3:1. The X510N only ever gets pushed to around 100W, and has been in place for around 3 years with no signs of damage or high SWR.

@@waynephillips1848 Thank you Wayne. Did you push 250W FM or SSB?

[@tylerhall6455]

I dont understand what you mean by "fake"... Is there someone selling these under the diamond brand and they are really made in china or something? If you bought these from a reputable dealer, then they shouldn't be fake at all. Also kinda doubt there is a counterfeit manufacturer out there selling these anyway, so a better explanation of what your point is would be helpful. Thanks for the vid and showing the internals!

[@waynephillips1848]

The chroming on the MH as new is cracked and bubbling, the fiber glass white clear coat on the tubes have been grinded off shorter, labels are missing from the body and internal connection points, from the supplied drawings incorrect section fixing screws supplied, also missing the assembly spanners and to top it off, it blew out one of the caps at 170 watts!!

It is difficult to understand you as your speech seems slurred.

[@andrewcollins3402]

Sounds quite clear to me. Perhaps you aren't used to the accent?
