Another part of my antenna experimenting equipment. A simple ugly choke for HF made with 30 turns of RG213 coax around a 4″ plastic pipe.
I needed a 1:1 balun to use with my home brew doublet but I needed it to go between the ladder line and the SGC-230 tuner so it needs to have stud terminals on both the input and the output. I took a look around and decided that making one was the best option.
It’s made using 11 turns of figure 8 twin lead on two stacked FT240-43 cores. See the pictures below…
