Verticale per 80m
La struttura portante è realizzata con tubi in fibra di vetro ma la radiazione proviene da un filo fissato al tubo

Vertical resonant around 3.5 MHz
The combination of wire is resonant around 3.5 MHz. With a 30 uH inductor, the resonance becomes about 1.83 MHz. A series 68-ohm resistor and 16 25 foot radials brings the feed point impedance

Verticale ad un quarto d'onda accorciata
la costruzione di una verticale monobanda, facile da realizzare, per la gamma dei 75/80 m

Shunt-Feeding a Short Tower on 80 and 160m
The shunt design has been through several iterations at my QTH. First was a single wire that was matched for 80m using an omega match
