WebIn the case of a 1:1 ratio current balun, core flux density or “magnetizing stress” on the balun core is independent of load impedance or load mismatch. Only common-mode current affects the core. What is the formula for 4 : 1 current balun? In the CobWeb’s case, 12.5*4=50. No complicated formula here, just basic maths and a bit of common-sense. WebAvoid using other types of baluns, such as ferrite sleeve or transformer type baluns. This antenna has a high reactive component at the feedpoint SWR of more than 2:1. The high SWR increases loss in ferrites and may cause excessive core heating, core saturation, or arcing in the windings.
