This work describes tehniques of antenna pattern measuring of fixed antennas on site. Performing these measurements is very important, because only when antenna is fixed and operating we can get real pattern, because of effect of soil as a conductor and some other effects. With these measurements we can help with antenna system development and provising of quality antenna covering. In first part I described some tradicional antenna pattern measuring tehniques, advantages and disadvantages of it. Some of these tehniques have various restrictions, however new tehnologies are offering us better and easier solutions for solving these problems. We are asking ourselves if there are some other possibilities to perform antenna pattern measurements. Nowadays there are numerous possibilities of using UAVs (Unmanned aerial vehicle) for different purposes, I am reaserching if we could use them for measuring antenna patterns on site. In this work I described some problems and restrictions we are facing and some solutions for them. There is description of such as UAV, suitable equipment and measuring antenna.
