Summary

Description
English: German submarine U-889 surrendered to the Royal Canadian Navy on 13 May 1945 at Shelburne, Nova Scotia, and was taken to Halifax. This image, taken 25 May 1945, shows an unidentified Canadian Navy rating examining U-889's radar detector antenna mast. This consists of two systems, the FuMB-7 Naxos tuned to the 9 cm wavelengths used by the UK's ASV Mk. III and H2S radars, and the FuMB-26 Tunis, tuned to the 3 cm wavelengths used by US radars. In this image the Naxos antenna is facing the camera, it consists of the two leaf-like antennas centered in the parabolic mesh reflector just above the rating's hand. This version of Naxos is known as Fliege, German for "fly", referring to the wing-like shape of the corner-reflector antenna's active elements. The Tunis antenna is above the Naxos, facing away from the camera. It uses a horn antenna, and from this angle looks like a cylinder. The entire mast rotated for detection around the boat, via a mechanical linkage to the radio room below. The system had the serious limitation that the antennas were not waterproof and had to be removed by the deck crew during dives. Behind the rating is a large loop antenna used for direction finding in the VHF band. On the left of the image, the cylindrical mesh grid is the "Bali" antenna used to detect 1.5 meter signals used by earlier Royal Navy radars.
