Verticale pour les bandes 80, 40 et 30m et 160m
It is a vertical mounted on the ground. The antenna operates roughly in 5/8 on 30m, half wave shortened on 40 and shortened quarter of wave on 80m. The impedance matching is performed at the base by an LC circuit L series / parallel C low pass configuration and a broadband transformer

Why Are Vertical Antennas Noisy?
E needed to establish resonance in helical antennas. Experience has indicated that a section of wire approximately one half wavelength long, wound on an insulating form with a linear pitch (equal spacing) will come close to yielded a resonant quarter wavelength
