ABSTRACT:
The objective of the invention is to compensate for the attenuation, in a direction (X,X), of the radiation from an antenna (5) mounted on a helicopter (1), including elements (12) which disturb the propagation of electromagnetic waves. According to the invention, at least one conducting wire (14) is fixed on the structure (1) of said helicopter, in proximity to said antenna (5), and positioned so that the electromagnetic interaction between said antenna (5) and said conducting wire (14) at least partially compensates for said attenuation of radiation.
