Coaxial air wound balun (choke) helper

prusaprinters

<p>This is a tiny clip designed to help in winding an air core choke balun (a few loops of coaxial cable which reduce common mode currents). See <a href="http://webclass.org/k5ijb/antennas/Balun-Air-wound-balun.htm">here</a> for more information on this.</p> <p>The clip is symmetrical (print twice to get a pair). Put coils in one clamp, rotate 180 degrees and slide the other clamp over the coils and into the cable locks.</p> <p>Print laying on clamp side (not on its bottom as the picture shows) to get the best durability.</p> <p>CABLE_DIAMETER = 5; // RG-58, 5 mm diameter NUM_WRAPS = 6; // how many turns of cable WIDTH = 8; // how wide the clamp should be DEPTH = 4; // how deep the clamp should be, needs to be &gt; CABLE_DIAMETER CABLE_SPACING=0.4; // distance between coils</p>
