I am reading the book "Understanding, Building, and Using Baluns and Ununs"
In the page 37 refers to 1:1 baluns. So it recommends that the core of a
Reisert balun (current balun) should have a permeability of 250 (160m)
or 125 (80 to 10m) or 40 (20-10m) for maximum efficiency. I have seen in
several articles that some guys make their baluns using mix 31 ferrites
(2631803802 has 1500) or ft240-43 (permeability=800). As I can
understand a higher permeability means a better chock or not? According
the book I gain efficiency with lower permeability but what I loose?
Have something changed after the book is written or not? Comments please...
