Obviously, normal precautions about bending radius should be observed.
It is NOT necessary for these chokes to have a tight bend radius to be
effective. I recommend turns of reasonable diameter that satisfy that.
Above about 15 MHz, turns should spaced widely apart except where they
go through the core. See the text, measured data, and photos.
