11G  Direction Finder
Frequency Range: 450 to 1,100 meters

Comment:

The 11G direction finder is designed for use aboard all classes of  mercantile vessels  as a navigational instrument. . It has approximately the same size and shape a' the type 11F which it is  intended to supersede.. The copper screened teak cabinet of the 11F, however, has been replaced by a sheet-brass box. This DF set is intended for use  with a Bellini-Tosi system.

Also refer to the 11G section in ths Marconi Review documment,
