Common-mode current choke CMCC for coax and controller cable
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..
Common-Mode Current insulator High curren insulation Coax impedance 50 or 75 Ohm Controller (analog) wires insulator
Good quality PTFE coax cable Low insert loss
- Quality PTFE SO-239 or N connector or F.
Common-mode filter for coax and controller cable Any devices with RF cable and controller cable (AC/DC) One of this model directly works with K9AY++ antenna system link
Version for K9AY++ RX antenna system link Universal versionall wires can be use
