Coaxial Dipole Driver for Yagi-Uda Antennas
The Folded Dipole exhibits the self-balancing behavior. The feed impedance is several times higher than the cylindrical dipole's

The VHF Quagi
The Quagi requires neither fine tuning nor careful handling. Many of these antennas have survived several years
Una Yagi da nove elementi portatile per i 144
Il boom e' realizzato con l'unione di tre profilati di alluminio di sezione quadrata da 20 mm e da 1 mm di spessore
2 Meter antenna cycloid dipole
The 6 and 2 meter cycloid dipoles, note the rain shield covering the rear portion of the matching sections along with the 1/2 wave coaxial cable delay line comprising the 200 ohm balun on each antenna
Yagi LFA 9 elementi per i 2 metri
Yagi lfa loop fed array per i 2m, con boom da 4.6m. l'antenna e' composta da elementi direttori e riflettori come le normali yagi
Matching transformers for 3 stacked yagi
Using three antennas often provides a good compromise between increased antenna gain
