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
Verticale senza trappole 14_21_28 without traps
Verticale per tre bande 20,15, 10 metri alimentata da un solo cavo coassiale da 52 ohm con tre whip radiatori
Verticale_40-20-15-10 only 3mt
Si tratta di una tipica antenna 1/4 d'onda, cioe' ad un quarto d'onda

This article deals with the function, repair and anchoring of verticals for short wave bands in gener
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

50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
