Balun 1:64 for end fed, PD7MAA- Build a legal limit current balun for 160 - 10 metersWind two FT240-61 ferrite core
Misure di una ferrite sconosciuta, IW2FND- In practice, just wind a coil around the core of the ferrite and measure the inductance
Creating a balun, G0KSC- For 50Ohm direct feed antennas, just a 1:1 balanced to unbalance transformer is needed
Balun di tensione 1:32- Toroid FT140 / 43 0.9 enamelled wire for primary winding
Circuito balanceado a um circuito desbalanceado, PY4ZBZ- Examples of BALUN made with coaxial cable stubs
