Note of OK1TEH: As I got info from Lars, the size of mesh was 12x12mm, it was covered by snow and while dish suffered from some smaller damages in past storms, the final storm with only 16m/s wind was the final one...

It's very sad view but we believe that Lars will not give it up and he'll make new one. GL Lars with reparation!!
