Radio beacon or "Funkfeuer", middle France

[Henofred]

Hello to all,

I am looking for the exact location of a radio beacon located between Bourges and Avord, middle of France. On a German navigation map (The I./NJG2 history book’s by Heinz Rökker) I saw that there was here a radio beacon named "FunkFeuer Saturn".
I discovered into the fields at 12 miles SSE of Bourges the remainder of a concrete support for a Würburg-Riese radar like two other concrete bases. One of them could be for the power station and the other one for the radio beacon??? All these remainders are located into a 0,5 miles radius.

That can be this radio beacon?
A last question; which are the basic structures and equipment for German radio beacon?
All the answers are the welcomes.

Best regards,
Frederic.
