Measuring the Radiation Pattern of Large FM Antenna System

The article presents a radiation pattern measurement performed on a real antenna system delivering over 100 kW of effective radiated power (ERP) in the FM frequency band. The measurement of the received signal was performed by a custom measurement device, „Pixla 1" with the use of a quadcopter DJI Matrice 300. This measurement resulted in the normalized radiation pattern characteristics of a given antenna system. Radiation pattern measurement was performed at various radii and at various heights with respect to the geometrical center of the antenna system.
