FuG 74 “Kulmbach”

The FuG 74 “Kulmbach” was an omnidirectional search radar operating on the 9 cm wavelength (S band). The radar electronics corresponded to the airborne radar FuG 240 “Berlin” but with a different antenna and display unit. The antenna was a tube antenna with a length of 6 m in front of a cylindrical reflector. It was mounted on a simple wooden construction.

The radar was completed in July 1944 and worked as a surveillance and target acquisition radar combined with the target tracking radar FuG 77 “Marbach”. This combination was called “Egerland Anlage”, of which only two were built until the end of the war.
