Abstract: One of the main problems of control of unmanned aerial vehicles (UAV) is restricted communication range  in VHF range. Thus potential range of flight taking into account constructive and technical possibilities UAV can exceed several times the maximum range of a communication range  with UAV. Possible variant of disambiguation is the organization of the channel of a radio service with UAV in range HF. However layout of transmitting short wave antennas on the body small-size UAV is challenging task. Electrical full-size antennas essentially exceed overall dimensions UAV, and their truncation for the purpose of setting within the case leads to essential lowering of antenna power gain. At the same time magnet antennas (for example, the resonance frame antenna) have essentially smaller overall dimensions at comparable characteristics. In research paper design of pre-production models original magnetic resonance frame HF antennas HF UAV of small range (SR) in executions by two variants is presented: for a ground distant operations control center and for onboard layout. Development was carried out in some stages: creation of 3D-model of the airborne antenna taking into account a construction typical UAV SR, modeling and calculation of characteristics of a breadboard model of an onboard variant of the antenna on the basis of a method of the moments, manufacture, adjustment and measurement of parameters of pre-production models of ground and onboard variants of execution. The fabricated antennas have small overall dimensions and characteristics comprehensible to practical maintenance.

Key words: the unmanned aerial vehicle, the magnet antenna, 3D-model, method of the moments, full-scale tests.
