The work demonstrates the importance of calculation of zenith angel of the primer magnetic field of the transmitter-station through knowledge of the coordinates of both transmitter-station and measure- area due to the use of special equations. They h
ave great importance for electromagnetically field measurements. The direction angels have been calculated for most famous transmitter-stations in some different areas of SYRIA (DRAA and SUWEDA). According to the results, these angels differed with the variation of coordinates of the transmitter in the same location, and some field measurements have confirmed this method.
