How to Build an UNUN
If you want to built your own UNUN, up F114-67 ferrite core, a few feet of #14 enameled copper wire enough for 9, bifilar turns
Homebrew
A universal matching transformer giving 1:1; 4:1 balanced and 9:1 unbalanced
il balun balanced - unbalanced
1:1 presenta al connettore una linea sbilanciata, avendo in ingresso un'antenna bilanciata
Les baluns sur tores en ferrite
It is necessary to consider the average power to be transmitted, not only the maximum power. Core saturation only occurs during power peaks
Toroid T200 for long wire antenna
Balun unun to feed a long wire antenna ideally without a tuner a 9:1 voltage unun design using a T200-2 Toroid core was selected
