Common mode choke

61 Material is a good wide band common mode suppression solution in the high frequency range from 25 up to 2000 MHz. If you use multiple cable turns around the ring core, the suppression will increase while the frequency will decrees. Single turn frequency range 200 – 2000 MHz. Multiple turns 25 – 300 MHz.

Wide band transformer

You can make excellent impedance transformers in the frequency range from 15 up to 200 MHz as well. Typical applications are end fed antenna impedance transformers, off center fed antenna impedance transformers or 1:1 Balun’s.
