How can you determine the permeability of a ferrite toroid core? I want to construct a 2:1 current balun. I have a box full of toroids, but have no idea of their permeability. They are various colors, mostly red, yellow, or blue.
Anyway, is the core material that important in a balun, or will any core that will handle the wire size and # of turns I need suffice? There is a lot of info online about baluns, but none I've found talks about how permeability affects balun performance. I want to use this on my 2 element quad to replace the RG11 stub match I'm using now. I never exceed 300w pep on my rig, and will be using #12 enameled magnet wire for the windings.
Any help and suggestions will be greatly appreciated. 73s
