The option of use of extremely simplified direction finding antenna array consisting of only three vertical vibrators instead of mul-tielement of nine vibrators as mobile direction finding is offered. Placement of such antenna array possibly, for example, onboard the unmanned aerial vehicle. In this case placement onboard the midget aircraft, such as a kvadrokopter is supposed. The model of such device and an antenna aray is presented, the algorithm of search of a bearing is given, the analysis of the direction finding characte-ristics received, in particular errors of definition of an azimuthal hade of an electromagnetic wave depending on a corner of arrival of a wave is carried out.
