The WM 20 series from the Dutch manufacturer "SIGNAAL" is found on ships with air defense missions. This tracking radar is used to mark aerial targets so they can be engaged with onboard anti-aircraft missiles. On many military vessels, this antenna type is combined with the CAS (Combined Antenna System) to extend the fire control system by one target channel.
 

 
 The model is equipped with a foundation ring. Since the support and buffer structure under the base is very delicate in the original and therefore difficult or impossible to print, it was modified, based on the original structure, to make it printable.
 

 
 The antenna system is printed in four parts and assembled using the included instructions.
 

 
 The mast installations / deck equipment shown in the pictures are not included.
