DF antenna raised or lowered?

Hi,

thanks to Anvart it is possible to have the DF antenna in SHIII raised
and rotating. Unfortunately it is only possible to have it either
raised or lowered, i.e., one has to choose one way or the other.

In most pictures of german submarines (I have seen) the DF antenna is
lowered. Does anyone know in which situations it was originally
raised and for how long? I guess for diving, in stormy weather and
also in dangerous (battle) situations it was mostly lowered, but I
don't know for sure. So, any comments are highly appreciated.

Cheers, LGN1

You knew, that DF antenna is not operated.
First I have made DF antenna rotation for Type 7c and Type 9 only,
but you asked to make it for other types of submarines too.
:hmm:

You have not full info. DF antenna rotation mod for Stock, RUB1.45, NYGM 2.2 and GWX exists with 12/21/2006.

Hi,

Sorry, I didn't want to criticize Anvart's work. I like it and I use the raised DF antenna. I just wanted to know how the antenna was operated historically.

@ Myxale: Thanks for the link, very interesting! Unfortunately, nothing is written there how it was commonly used (raised 24/24,...?).

Cheers, LGN1

As it should be understood?

I agree with ref. I'm pretty sure they didn't rotate automatically; the radioman rotated it by hand to get the direction of an incoming signal. Hence "direction finding" antenna.

Hey although it's motorised therfore not accurate, you got to admit, it looks cool!:D
Thanks Anvart, got it all up and running, gone through a patrol with no CTD's.:yep:
