RadarGen has overcome numerous instances of obsolesence by alternative design or choice of currently available components.

A Design Change Report is issued to the Customer, with full technical details.

RadarGen assume full responsibioty for such changes  


RadarGen have successfully designed and constructed units and modules for Watchman and other radars.

Together with partners world-wide can fulfil a variety of requirements using the latest technology and design methods. 

SLS and DMLS  methods are now employed to form enclosures and components (such as corona shields used in high-voltage areas of transmitters). 

A sophisticated array of high-temperature plastics and suitable metals are formed directly from 3D CAD/lithographic files, rendering the original resin-cast methods obsolete.
