The authors have developed a numerical algorithm for analysing the electric characteristics of the sys-tem of vibrators arbitrarily located above the ground. The algorithm allows one to calculate the antenna radiation patterns corresponding to the harmonics (subharmonics) of the fundamental radiation, the frequencies of intermodulation interference, the pattern distortions, and the input impedance change caused by the installation of additional antennas on a given object. The votage induced by the nearby transmit antennas can be calculated as well.
