Abstract: 
The penetration of ultra low frequency (0.01 –100 s-1) electromagnetic (ULF EM) radiation throughout ionosphere are calculated numerically for source in the lithosphere and in the magnetosphere. The changes of perturbation area shape during propagation in the ionosphere are investigated for different «antennas» types in the lithosphere which excite this EM radiation. The wave and spatial characteristics of penetrated into upper ionosphere ULF EM field are determined. The influence of altitude profile's main parameters of ionospheric plasma and geophysical condition onto the penetration effect of ULF EM radiation throughout ionosphere is discussed.
