[Milsurplus] German electronics innovations, WW2

[Tom B]

Hello All,

>I was thinking today of these features i have noticed about German WW2
>radio electronics, and wondering if in fact these were the first appearances
>of such innovations:
>5) Tape antenna ( built with multiple layers of tape-measure like metal. 
>( Feldfunk series radio, also maybe KlFud ).  Seen in USA PRC-8, 9, 10

I have noticed that the Russians adopted many of the German innovations
except the tape antenna.  They used the Kulikov antenna that is made up of
metal spools held together with a steel cable.  I would have thought that
the relative ease of producing the tape antenna would have made it a clear
choice.
Does anyone know the history of the development of the Kulikov antenna?
