Light atoms usually show only a small anomalous dispersion effect. In this case, the Flack parameter can refine to a physically unrealistic value (less than 0 or greater than 1) and has no meaning. This parameter, introduced by H. D. Flack [1] became one of a standard set of values being checked for structures with noncentrosymmetric space groups.
Beside being towed, the Flak 30/38 could be mounted on a variety of vehicles, ranging from being mounted on the rear platform of cars, trucks and half-tracks, including vehicles such as the Sd.Kfz. 10/4 and 10/5 (Flak 30 / Flak 38), Sd.Kfz. 11/1 (Flak 38) to being used for dedicated anti-air vehicles such as Flakpanzer I and Flakpanzer 38(t).

FuMO 1 - Calis A: Its 6.2 x 2.5m antenna consisted of 2 rows of eight full wave vertical dipoles. Its wavelength was 82 cm and its range depended on the height it was installed above sea level, but typically was about 15–20 km. [ 7 ] Given the frequency low angle reflections from the surface, also known a clutter would have been an issue.
The 2 cm Flak 38 auf Panzer I Ausführung A, commonly known as the Flakpanzer I, [1] was a rare self-propelled anti-aircraft gun conversion of the Panzer I in use by the military of Nazi Germany during World War II.
Thus a more powerful successor, with an armament that hit harder and at longer range, was produced which eventually replaced it. Known as the Flakpanzer IV Ostwind ("East Wind"), the successor was equipped with a single 3.7 cm Flak 43. [1] [2] Side view of Wirbelwind at CFB Borden
The 3.7 cm Flak auf Fahrgestell Panzerkampfwagen IV (sf) (Sd.Kfz. 161/3), nicknamed Möbelwagen ("Moving Van") because of its boxy shape, was a self-propelled anti-aircraft gun built from the chassis of the Panzer IV tank. It was used by the Wehrmacht in the European Theatre of World War II. Möbelwagen in northern France, June 21, 1944
German submarine U-441 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II, which served for a short time as an anti-aircraft submarine under the designation U-flak 1. The submarine was laid down on 15 October 1940 at the Schichau-Werke in Danzig as yard number 1492, launched on 13 December 1941 and commissioned on 21 ...
