Loop Antenna Multiband Horizontal
This multiband antenna covers the 80, 40, 30, 20, 17, 15, 12, 10 and 6 Mx Amateur bands. Multiband operation is achieved by use of 300 ohm balanced line fed to an antenna tuner

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
