Common mode choke
52 Material is a very good wide band common mode suppression solution in the frequency range from 4 up to 150 MHz. If you use multiple cable turns around the ring core, the suppression will increase while the frequency will decrees
Wide band transformer
You can make excellent impedance transformers in the frequency range from 1 up to 60 MHz as well. Typical applications are end fed antenna impedance transformers, off center fed antenna impedance transformers or 1:1 Balun’s.
