And as someone who has built several Baluns, these do not even say what the impedance ratio is. A good Balun will have the right impedance ratio for the intended job, and the right internal impedance between the pairs of wires on the cores to provide a low return loss. It is not easy to get good performance over the full 160 to 6 meter range. These do not look like a good choice, unless you want to lose lots of signal in the Balun.
