Avvolgimento trasformatori in ferrite
Per ottenere le migliori prestazioni da un trasformatore di impedenza avvolto su toroide o ferrite binoculare occorre provarlo su un carico che abbia la stessa impedenza della Beverage, tipicamente 450 Ohm

Baluns for 88-108 MHz
You can make a simple current balun by coiling coaxial feedline in a particular way

Balun 1:6-Balun for dickerdipol
The balun is suspended at a distance of about 1 m from the mast

Balun 1:1 Larga banda da 1.8 a 50 MHz
Questi due BALUN 1:1 sono indicati per potenze non superiori ai 500 Watt
