Well the antenna movement isn't animated. Probably not worth the effort.

Bf-110 has a rotating D/F-loop at the bottom of fuselage behind the wings



In early variants, the loop antenna had to be manually rotated with this thing:

I recall that Ju-52 and other older twin engine planes had also manually rotated D/F-loops.

Later Bf-110 G-2 what we have already flyable has automatically rotating antenna and even later G-4 has this replaced by iron ferrite coil which is inside the fuselage like in Ju-88.

Many allied bombers have rotating D/F-loop inside a teardrop shaped cover. Check for example B-25s in game.

Some smaller planes have fixed small iron ferrite coils which work like loop antenna. Almost all LW late war single engined planes have either small fixed loop or ferrite coil. The idea of D/F-loop antenna is that when is facing directly towards (or away) from the radiating source like NDB, the induced current going through the antenna is zero.


So instead of rotating the antenna itself, plane must turn directly towards/away from beacon and then AFN gauge shows no deviation (needle centered). Getting a triangulated position from two beacons requires more effort with fixed antenna.
