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

Cobweb Antenna 20m - 17m - 15 - 12m - 10m
This antenna, I made, not only covers 10-20m but tunes quite well to 40 and 80, has a reasonable swr at 6m! and a good swr from 120mhz to over 150Mhz
CobWebb Antenna for the 14,18,21,24,28 MHz Bands
The Cobwebb is a very practical multi-band antenna my end fed wires need to be changed to cover the 5 bands with a very acceptable performance
Dipole for 20 and 40m bands
By experience, I have noticed that a 20m band dipole antenna must be elevated by at least 8m above ground to perform well
Dipolo a doppia polarizzazione
Nei collegamenti a grande distanza,e' ormai noto la superiore efficienza delle antenne verticali rispetto al dipolo orizzontale
