Description

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. This version is directly designed for K9AY++ antenna system.


Using

  • Common-mode filter for coax and controller cable
  • Any devices with RF cable and controller cable (AC/DC)

Main functions

  • Common-mode current insulator
    • High current insulation
    • Impedance 50 or 75 Ohm
    • controller (analog) wires insulator
  • High quality PTFE coax cable
  • High quality connectors
  • Low insertion loss
  • IP56 box - recommended to protect it against water
  • Feeder size 100x100 mm
  • ASSEMBLED VERSION

Parameters

  • Control cable voltage up to 100 V DC/AC
  • Maximal current on wire up to 300 mA
  • K9AY++ version 7 wires + GND
  • Version for K9AY++ RX antenna system classic or remote version


Available as

ASSEMBLED: ready to use
KIT: all parts + PCB and IP56 box - KIT VERSION
Connectors: PL SO-239 or F
