H-Field Ferrite Rod Antena Parameters
Hi All,

I'm trying to build ferrite rod antenna from spare parts.

I think I'm missing this information but I still can't find it on the forum. What are the typical parameters of the antenna?

I mean

1) Length
2) Wire diameter
3) Number of coils
4) Impedance
5) ...

1) 200mm is better than 100mm, but not doubble
2) 0,25-0,40mm Ø
3) One for every channel
4 ) ???
