20 Meter Top Loaded Vertical
A top loaded vertical antenna has several advantages over the conventional vertical, but the biggest advantage is that it's shorter in length

Verticale Multibanda per i 10-15-20-40-80 metri
Per la sua realizzazione ho usato due tubi da m 5,20 l'uno, giuntati per una lunghezza totale di m 10, 15
Verticale per 30/40 MT
I radiali , nel mio caso,sono 6 ( 3 per i 30 e 3 per i 40 )
Verticale trappolata per 12 e 17 metri
La misura dei radiali per i 12 metri e' all'incirca di 3,10 m, mentre per i 17 metri la misura e' all'incirca di 4,20 metri
Vertikal for 20 meter
Parallel resonant circuit, wherein the coaxial cable was rolled up and the coaxial cable outer shell was tuned with a capacitor to the useful frequency TRAP
Vertikalantenne fur 40 und 80m
Vertical multiband antenna for 40 and 80m. However, a groundplane requires a good radial network, otherwise it will not work well. I laid some fence mats and 10m long wires around the base
