Abstract :
The purpose of his article is to provide the calculating formula of the electromagnetic field generated by the horizontal polarized broadcasting television transmitting antenna in space. The ground is considered as homogeneous, linear, and isotropic conducting medium. The space field strength is calculated through the sum of direct and reflected wave. Finally, a comparison is done between measured results and the calculated results using the formula taking the ground as ideal conductor a conducting medium and without considering the ground effect respectively. The advantage of the algorithmic is indicated by the analysis.
