DF antenna of Blenheim

[Alfa Oscar]

Hi!
Does anyone recognize this kind of DF-loop? Some of the first Finnish air force Blenheims were equipped with Marconi type AD.77/6872 wireless. I wonder if this square loop belonged to it or to finnish made P-12-14 radio set? Any specs and further information of this antenna are wellcome.

I'm relying on my memory here....but I recall this type of ADF loop can be seen on British examples. If I remember correctly, it in in stowed position in this photo. When expanded it forms a box shape. You can just make out the locations of the hinge brackets.

Just went through this book, 157 pages of Blenheims, nothing like the above photo

Thanks for answers.

So far, I have found pictures of 11 different FAF Blenheims, that had this antenna. Mostly from books of my personal library or from: SA - kuvagalleria
These planes were Mk.I and Mk.IV types bought from UK in 1930s.

Any photos of RAF (or civilian) aircraft I have´nt found.

It is a pre-war/early-war folding DF loop used by RAF Coastal Command for sure (possibly other Commands also) with the R.1082 (and R.1155?) receivers.

Great!
Many thanks ThomasP!

Now I can be sure it´s british origin...not our own invention.
