Details
A typical antenna has a symmetrical output with an impedance of 300 Ω, while the coaxial cable is an asymmetrical load with an impedance of 75 Ω. Therefore, in order to connect the antenna to the coaxial cable while maintaining matching (using devices of the same impedance throughout the system), it is necessary to use an intermediate element, i.e. a symmetriser. The symmetrizer is a passive device that uses a transformer to change the impedance and transition from a symmetrical line to an asymmetrical one.
