The Direction Finder Antenna Loop was located on the starboard side of the bridge. It was used to detect and get bearings from the radio signals of Allied surface ships. There are two known styles found on the Type VIIC's, an early-war and a late-war versions. The loop in both versions are the same diameter of approximately 800 millimetres (2 ft 7 in). The only visible difference between the two version is the additional antenna added along the centreline of the antenna loop. This additional antenna is approximately 2,300 millimetres (7 ft 7 in) in height and is attached to the base of the antenna loop.
The 3-D model is base on original German measurement and wartime photographs.
