RF electromagnetic measurements in a rural environment

Radioelectrical power measurements taken in the 20 MHz-3 GHz frequency band in a typical rural environment are presented. They show that the spectrum is very clean outside frequency band allocated to land, aeronautical and maritime radiocommunication and more particularly in frequency bands allocated to radio-astronomy, spatial research, remote sensing, radio navigation. They show that the site environment does not suffer from strong electromagnetic fields able to create non linearity in the relevant frequency band. Calculated to the antenna level, electric fields are weak compared to standard limit values legal in France and in the European Union.
