DC-3 Radio antennas
High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 MHz. It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred metres).
How to Use the ADF Radio.
An Automatic Direction Finder (ADF) is used for exactly what it says: to find the direction of not only a radio source (i.e: a radio tower), but also to use the bearings (locations) of two radio sources and the headings (directions of travel) of their signals in order to pinpoint the location of the aircraft receiving them.[1]
