Abstract

L'invention a trait à une antenne de véhicule comprenant un conducteur disposé à la surface du pare-brise ou à l'intérieur de celui-ci ainsi qu'un étage amplificateur accordé possédant un transistor d'entrée à haute impédance ohmique dans le domaine de la modulation d'amplitude et muni d'un circuit de réglage ajustant l'amplification de l'antenne en fonction de la tension de sortie de son étage amplificateur. Elle permet d'éviter la saturation des récepteurs radiophoniques des véhicules et notamment des automobiles.
