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

50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
