What is a balun:
A balun, short for “balanced to unbalanced”, is a device that converts a balanced signal into an unbalanced signal. But what exactly does that mean? When an antenna receives a signal, it absorbs radio waves from the environment. This signal collects at the ends of each antenna element and creates charges at the feed point/nodes. These charges carry the desired signals that we want to transmit to the radio.

The differences between baluns and UnUns:
The main difference between these two is that baluns are designed to match impedances between balanced and unbalanced circuits, while UnUns match impedance between two unbalanced circuits.

The unbalanced solution:
To correct this imbalance, we need a way to convert the balanced signal into an unbalanced signal. This is where baluns come in. There are two common designs: the coaxial balun and the coil balun.
