If you have time and (maybe) muse, could you give a few words about this?
...
I mean this. A fresh project. 15-m-Antennmast, red=omni-antenna and lightning-protection.
The n1x formula is a more ore less good guess, because in this case the stiffness/mass of the
omni/lightning-protection is unknown.

Looks great :-) Was the frame's geometry designed entirely in FreeCAD or imported from external CAD software and only analyzed in FreeCAD with its FEM module ? What about the technical drawings - which software did you use to create them ?

Freecad FEA was done mostly for fun and to check this great software. It was drawn entirely in FreeCad. I wasn't able to import anything with good results (unfortunately). Technical drawings was done in basic cad software (ZwCAD).

FreeCAD also has a decent module for 2D documentation (TechDraw), did you give it a try ? It could be sufficient in your case.

Can you tell us where this tower is located ? Is it actually in Poland as we suspect ? I could see it one day since I live in this country ;-)
