Alberto Virtuani wrote:Hi Dave,
If I understand correctly, this means that Seetakt was able to search surface targets, provide rangefinding for gunnery and also perform air surveillance.
However, I don't understand how this could be done by a flat antenna: I imagine the whole rangefinder (armored aft) had to be rotated continuously to perform such search, and also that this antenna had a quite large lobe vertically to allow an horizontal antenna to cover also high altitude flying airplanes. Is my understanding correct ?
Were the Sumatra antennas positioned around the squared top of the main director or on the hand rails of the "Vormars" ? I was thinking they were in the same position as in Tirpitz, that is around the director.....
Do you confirm they were 4 around the Vormars and how many around the main mast railings ?
Are the sumatra the "butterfly" dipoles like these (my very bad drawing...)
Are you sure about that ? I have never seen any photo of Scharnhorst with such a large antenna (do you have any?), Tirpitz received FuMo26 only in april 1944 (AFAIK)....
Thanks again !
