웹2024년 7월 12일 · RF balun designs are most commonly associated with core-and-wire transformers, but can also be realized through coaxial and coupled stripline technologies. The behavior of baluns and ununs was introduced in Part 1 of this series, where we established that both these devices are designed for impedance matching purposes. 웹If you still don’t have any channels after step #5 above, try a different coaxial cable between the antenna and the TV set. If still no channels, bypass the power inserter. If there still are no channels, try replacing the balun/matching transformer. If this doesn’t resolve the issue, it may be necessary to replace the antenna.

웹Simple 1:1 voltage balun: Simple 1:1 current balun: A voltage transformer type balun uses magnetic transfer (transfomer action) to produce a balanced signal at the output.The 1:1 impedance transformation is achieved by making the impedance of each winding the same.
