WebOct 26, 2024 · There are two types of baluns used for this purpose— current baluns and voltage baluns. A current, or Guanella, balun ensures that identical currents flow in the terminals of the attached load, such as an antenna. A voltage, or Ruthroff, balun ensures identical voltages at the load terminals but does not ensure identical currents.
