Balun 4:1
Hi! I'm building a homebrew T antenna tuner and would like to make the
4:1 balun for it. As I live in Brazil (northeastern and the poorest part of the country) it is very difficult to find ferrite cores in my city, i would like to make it with ferrite rods from MW radios. I have three ferrite rods with diameter of 3/8 inchs and lenght of 4 inchs. I know it is possible to use them to make the Balun, but I would like to make one that can hold the maximum of 100 to 150W (it's for my Yaesu FT757GX use). Does anyone have any project? I have small experience in electronics, so I would like detailed instructions to not make any mistake. 73, Yvson - PR7BOK |
