WebA Voltage Balun is one whose output voltages are equal and opposite (balanced with respect to ground). True balance occurs only if the balun’s load is symmetric with … WebA Balun is used to match a balanced line to an unbalanced line. An Unun is used to match an unbalanced line to another unbalanced line. This is a 4:1 Current Balun.That means it can match a 200ohm antenna to a 50 feed line. If you plan on stringing up a dipole you use 2 equal lengths of wire with the Balun in the middle. can eggnog be warmed
