Common-mode current choke CMCC for coax and controller cable

wiki order

Common-mode choke coils work as a simple wire against differential mode current (signal), while they work as an inductor against common-mode current (noise). This box is designed as a common-mode filter for RF cable and also for analog AC/DC controller wires. One of this version is directly designed for K9AY++ antenna system, second one is Universal..
