A Balun is a joint device that connects a balanced line (line that has 2 conductors with equal currents in opposite directions) to an unbalanced line (line that has just one conductor and a ground). 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. Baluns also allow a device to be placed an extended distance from the system it is connected to. CAT-5 Baluns enable system expansion in structures already wired with CAT-5 cable. Because they have passive circuitry Niles CAT-5 Baluns require no AC power and can be located almost anywhere.
