SK Sendestation plan.

My plan less two Tobruk's, I do not know where where they were situated.
Built by the Todt Org. I do not have a full time line, but it must have started early in 1940 as a Luftwaffe radio guidance for the bombing of Britain. This would have been a FuSAn 721 Knickebein. This was a concrete circular base with a large square panel and usually a wooden shed attached at its rear and it turned on a steal rail 360°. This with many more situated from K1 30 Klepp Norway to K11 30 Saint Fiacre. There were two more but they are out side of France. There are several websites that explain their uses and I will add links to them.
Next to arrive possibly FuMG 402 Wassermann but I am not too sure as there are no remains of a large bunker to hold its workings.
Next a See-Elefant. Early warning radar, I am not sure this type would have been here as its usually used with the Wasserman system of radar.
