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 multibanda 12m-17m-80m
Un dipolo per 12m-17m trappolato e' lungo circa 3,40 m per braccio , quindi 6,80 m totale

Dipolo HF 80m - 60m - 30m
Ho deciso di costruire un dipolo che mi permettesse di operare sulle gamme 80m-60m e 30m

Dipolo multibanda G5RV
Questa antenna risuona sui 10-15-20-40-80, il tratto di discesa in piattina deve essere il più lontano possibile da parti metalliche
