Witryna10 cze 2024 · Measuring a Common-mode Choke's Resistance and Reactance: We need to quantify the resistance component of a choke's overall impedance. This measurement can be made with a Vector Network Analyzer (VNA). But, if using a VNA, do we make a reflection measurement (S11) or a transmission measurement (S21)? WitrynaFor an antenna, the purpose of a choke balun is to create a high-impedance to common mode currents that would flow on the outside of coaxial cable shielding. These common mode currents can cause all kinds of problems such as RF in the shack, matching problems, and others. So, minimizing common mode currents is a good thing.
