A typical antenna has a balanced output with 300 ohm impedance, while a coaxial cable is an unbalanced load with 75 ohm impedance. So, an impedance transformer (often called balun) must be used. A balun is a passive device which uses a transformer to change the impedance and character of the output (balanced/unbalanced). Usually, such transformers have standard construction with ferrite core. Some transformers are optimized for working in a particular band, e.g. C0001 for channels 1-12, while baluns working in channels 21-69 are mostly made in the form of flat PCB transformers, such as the C0002 item.
