Default Ferrite core : yes it works... Now for the antenna...

The turns ratio is 1:4 and the impedance ratio is 1:16. In other words
the impedance ratio is the square of the turns ratio. This is a little
high and I would go for more like turns ratio 1:3 for impedance ratio
of 1:9, which would be 50 ohms : 450 ohms. For example you could use 3
turns primary and 9 turns secondary.

Another question please... Will a 2 / 6 turns balun behave the same as a 3 / 9
turns balun ?

I suspect not, but what will be the difference ?

Thanks again for teaching a newbie...
