What is a Balun?
A Balun is a device that joins a balanced line to an
unbalanced line. A balun is a type of transformer: it's used
to convert an unbalanced signal to a balanced one or vice
versa. Baluns isolate a transmission line and provide a
balanced output. A typical use for a balun is in a
television antenna. The term is derived by combining
balanced and unbalanced.
