Abstract

In the article the analysis of the fading deepness of the signal at the receiving antenna input of the aircraft flying in the air space between the repeater station and a power line were presented as well as it was determined if the level of fadings generated by signal reflections from power columns has destructive effects to the quality of radio link used. To this purpose, the analysis of the terrain between the repeater station and individual power columns was carried out. Basing on the analysis results it could be accepted that the propagation of the radio link at the sector of the ray reflected, i.e., the repeater station antenna, reflecting surface of particular power columns and receiving antenna installed on the plane, can be modeled using the free space propagation model.
