The automated system for complex measurements of antenna systems is designed for measurment of parameters for largescale antenna (dimensions up to 8x8 m2 and mass up to 5 tons). Installation error of an angles at position of the researched antenna at azimuth and elevation planes doesn`t exceed ±0,05°. Mode control for system functioning in particular, working frequency setting, sweep speed and signal level is established by the operator with the help of computer. For connecting of operator`s place with the transmitting position and the reference channel Wi-Fi is used. Automated system allows it to measure directivity diagrams and frequency characteristics at frequency range 1…26 GHz. For influence reduction of signal reflections from local objects investigated antenna and container with apparatus of the reference channel are located at the hill of 7 m height and the container with transmitting apparatus of mobile position is located at extensible mast of 30 m height.
