Nota adicional1
It is important that the near-field or in-duct measurements enable a sufficiently accurate prediction of the changes to engine noise in the far-field.
Contexto
Mounting height should be sufficient to prevent the antenna being covered by snow, or being interfered with by maintenance personnel or ground traffic. The antenna should be sited so that any metal structures, such as air vents, pipes and other antennas are outside the near-field effects of the antenna.
