Dickerdipol antenna multibands with balun
The 5 radiating wires are spread to 1.2 m. with un balun 1:4
Dipolo acortado
The calculation of the linear load is made by adding 30% to 30% removed from the irradiator, the dimensions being as follows, Total length of the irradiator: 5, 51 meters Length of each linear load: 1.54 meters
Dipolo HF 80m - 60m - 30m
Ho deciso di costruire un dipolo che mi permettesse di operare sulle gamme 80m-60m e 30m
G5RV antenna 40/10 & 80m - 40-10m
I bracci terminali possono essere istallati o paralleli al terreno oppure a v invertita
