English term or phrase:loop antenna
Automatic Direction Finding (ADF)
Automatic direction finding is a direct derivative of the direction finding systems used from about 1930 onwards.
It uses a principle of looking for a null point on a >loop antenna< and from there being able to distinguish the ground station location. In the early days it was the most effective navigation mechanism, but its use today is limited to a secondary or backup system. It is still very much in use on general aviation aircraft.
