Balun 1 4

웹For example, if you have a 4:1, then the device has a high impedance that’s four times balanced to unbalanced impedance. The goal of the device is to lower the input impedance and maintain the output impedance. Baluns usually come in 4:1, 6:1, and 9:1, but individuals can experiment with the frequencies they’re looking to emit. 웹A GENERAL PURPOSE TUNER BALUN: The selection of components for your tuner balun will depend on the required bands it must cover as well as the power level it must handle. In a perfect world, we would have 3 different baluns, one for 160/80, one for 40/30 and one for 20-10m. We would swap them in and out as necessary.
