At this point, there is a good idea to use CMCs for the power lines that supply the RF communication equipment (SMPS power supplies, linear power supplies etc.). Potentially, the current mode currents can appear both at receive and transmit, so installing a CMC in the feedline path will significantly reduce the received noise and improves antenna's system overall performance. Because the CMC in discussion does not perform a a matching function, it can be named a 1:1 current balun. Because it forces the current at its output terminals to be balanced, the CMC are often named 'current baluns'. CMC exhibits high impedance to common mode currents/signals and does not affect (significanlty) the usefull differential signals transmitted through the feedline/coax. Often reffered to as a Feedline Current Isolator, a Choke Balun, a RF Choke, a 1:1 Guanella Balun (after its inventor) or a 1:1 Current Balun, the CMC is in essence a signal conversion/isolation device that suppresses (by its resistive behaviour) the current mode currents by forcing them to be balanced at its terminals (equal in magnitude and opposite in phase), even if the connected signal source or the output load are highly unbalanced.

We will try to clarify what is the common-mode current and when this current can be a problem' in RF systems like ham-radio. This article is an attempt to clarify more aspects about common mode chokes and line isolators used mainly in EFHW antennas ( E nd F ed H alf W ave). The external outside antenna tuners are the most efficient when you are in need to optimise your antenna to your radio if the S.W.R. Common Mode Chokes and Line Isolators in EFHW Antenna Systems. We have stock and are ready to transport JC-4s tuners.
We did arrange a complete new redesign of the control box. We selected a new company in The Netherlands who is producing our prints.
