...to which I replied, "I'll measure one and report back." I just wound a "W1JR Balun" as specified, using an FT-240-61 toroid and RG-303; then I measured its common-mode impedance (between the ends
Would there be a recommendation to have one design for the high bands (40-160M) and one for the high bands (10-30M)? If so, how many turns through the core would be recommended for each? Tnx N2TK, To
Hi Tony, You can surely do what you suggest. The 12 turn one on a 2.4" OD 61 material toroid is very good from 40-10 (and even to 80 meters) meters with high impedance and no resonances. To get to 16
