Territorial distribution of radio short-wave frequencies signal from the transmitter with "Rhombus" Aerial

The design procedure of spatial distribution of level of a signal on territory from the transmitter with set power characteristics and diagrams transferring aerials orientation (antenna) is considered in the article. The obtained data can be used at the planning stage and while organizating distant ionospheric radio communication between air traffic control points and long range civil aircraft, and also for communication (level) improvement by giving recommendations and offers for choice of aerials, correction of orientation diagrams characteristics, transmitters capacity changes, etc. The results of calculation of levels of electromagnetic fields of short#wave frequencies transmitter working with Rhombus aerial from Moscow area to European part of Russia and the Ural Mountains are given as an example.
