Ft140-43 core
WebTaking an example of an FT140-43 or Fair-rite 5943002701 with 10 turns at 21MHz. Inductance of an inductor wound on a high permeability core can be given as . where A µ , N is the number of turns, A is the cross section area of the core, r is the radius of the core, and µ is the permeability of the WebAn alternative is to use an FT140-43 toroid, which is smaller (the “140” refers to the diameter, so 1.4 inches), which is good for at least 50W. However, some reports say the smaller FT140-43 doesn't really give sufficient inductance on 80m and there are reports of it heating up on 80m. I found that the FT140-43 DID work on 80m and
