WebImpedance transformers and feedline chokes can be configured with either balanced output (balun) or unbalanced output ( unun). A few definitions in picture form: BALUN … UNUN Here are examples of UNUN output configuration differences: Sleeve Unun Examples (click on image for more info) WebOct 26, 2024 · A choke balun never changes the impedance inside the feed line. It only blocks CMC to perform the balun function. However, there are some types of baluns that do; a 4:1 ratio is the most common. A 4:1 balun can be made from sections of coaxial cable or from parallel wires wound on a ferrite core—a transmission line transformer.

WebMar 11, 2024 · 4. The advantage of using coax for a 1:1 choke-balun is the constant Z0 of 50 ohms. As can be seen in the following graphs, the only time a 1:1 choke-balun accomplishes a 1:1 transformation is when it sees 50 ohms at its output. Any other impedance at the output causes an impedance transformation because the SWR is not 1:1. WebAnswer (1 of 17): Amateur radio operators tend to group all devices that are connected between the feedline and antenna into “baluns”. In some cases, an RF choke wound of the coax can serve as a current balun, as it permits a good separation between common-mode currents travelling along the outs...
