I'm still searching for a replacement of the FT140-43 (core efficiency ~80%) in my portable EFHW xOTA-Antenna design. The nowadays so popular Fair Rite 2643251002 toroid is a bit chubby, so I'm playing around with the smaller 2643101902 core now. Looks promising, ~90% efficiency (-0,5dB loss). Now I need to check with a real antenna and under load. #hamradio
