VHF-UHF Yagi Antenna Feed Design
Balanced feed line are readily available in various impedances 75/300/450 ohms, but the use of a balanced feedline presents some physical requirements that are not easy to get around

Yagi 7 el. Per 70 cm. Ecologica
La lunghezza totale del boom e' di circa 1m. poiche' dietro al riflettore e' previsto il fissaggio al mast. La sezione e' 1 x 2 cm

Yagi 9 elements
The first director can be moved forward or backward to search for the best ROS

6-Element yagi for 144 MHz
The design has been performed using yagimax2 software and practical tests. I created several prototypes before I found out the correct measurement
