Web26 de fev. de 2024 · How a Balun Works. A balun works by choking off the outer current sometimes found on the shields of coaxial cables. This function helps restore balanced antenna operation which is required for proper functioning. In respect to dipole antennas, the term balanced means currents flow equally on each side or arm of the antenna. WebBalun is an acronym for BALanced to UNbalanced, which describes certain circuit behavior in a transmission line, source or load. Most communications applications …

WebCurrent baluns are the balun of choice in all but very specialized situations, because they work better than voltage baluns in most real-world systems. In 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. Web6 de out. de 2024 · From personal experience, a good 1:4 balun (50 to 200 Ohm) doesn't necessary work as a good 4:1 balun (50 Ohm to 12.5 Ohm). You can wind just a 4:1 transformer and use it with a 1:1 balun though. Another simple way to match any impedance is to use an LC-network. There are a lot of online calculators. Personally I …
