[Antennas] Baluns

[George, W5YR]

A voltage balun produces equal voltages at its balanced terminals. If the
impedances to ground of the balanced antenna system are the same for each
side, then the same current will flow in each side. This is almost never
the case in the real world. So we use current baluns which are designed to
force equal currents into each side of the balanced feedline and thus more
or less equal currents into each side of the balanced antenna. This
produces the most effective operation.

The voltage balun has a few restricted uses but for most amateur work, the
current balun is to be preferred. And the 1:1 ratio on average works better
than a 4:1 or other such ratio.
