In order to improve the effectiveness of my 50 MHz station, during the spring 2001 I’ve designed with the Quick Yagi 4.0 software a 3 elements Yagi.
Targets of my design were clean pattern rather than gain optimization and wide band to get an easier matching.
Here how it looks like the QY screen with my antenna optimized
and tested in my garden,
works in the QRM of the “neighbors” (many , with a very clean pattern that helped a lot to 6m station active in Italy), but all in all I got disappointed for the low gain. To be honest, I must confess that it was installed at only 4-5m above ground (and just 2-3m above the roof). This fact, probably effected seriously the gain and especially the radiation angle performances.
Pierluigi Poggi since his childhood has been attracted from technical stuffs and gears, being a very curious guy. He built his first Xtal radio when he was just 9. Today, we would call him “maker”. When he turned to 21 became radio amateur, with call sign iw4blg.
Since then, he developed many radio gears and felt in love with space communication, becoming an EMErs and a satellite enthusiast. His great passion led him to experiment a lot on the higher bands, up to pioneering several THz (lightwaves) QSOs on the early ’90.
Beside to this passion to the radio communication and modern technologies, he like to study, experiment, understand-why, then, write and share, or better, spread the knowledge. This fact led him to became a well renowned contributor of electronics magazines with more than 95 articles published and author of 14 science books.
