Investigating propagation curves of electric field intensity of Jigawa Medium Frequency Radio Transmitter

Abstract: This study investigates the variations in the electric field intensity of Jigawa Medium Frequency (MF) radio signal along some radio routes using propagation curve. It also compares the propagation curves due to measured field intensity with those predicted by GRWAVE software using the ground electrical conductivity of the routes. The need to predict propagation curves using GRWAVE software and compare same with empirical curves to ascertain the adequacy and suitability of the predicted curves to characterize … Show more
