Abstract
Ce signal est constitué d'un cylindre vertical transparent (1) dans lequel sont creusées deux cavités coaxiales coniques (2, 3) dissymétriques et opposées par leurs sommets qui sont reliés par un raccord cylindrique vertical (4). Le cylindre est supporté par une base (6) équipée d'un réflecteur parabolique (9) et d'une lampe (10) tandis que la partie supérieure du cylindre est coiffée d'un chapeau conique (16) qui se termine par un petit cylindre transparent à extrémité conique (19).
