WebI am preparing to construct a resonant, center-fed, horizontal dipole. I have seen people use baluns at the feedpoint of the antenna, and some people swear by them, but I have never gotten a satisfactory answer on why … WebA BALUN IS ALSO sometimes used as an impedance transformer. Normally a balun has a 1:1 impedance ratio between its input and output sides. By modifying the design of the balun, it is possible to have other impedance ratios. Examples: 4:1, 6:1, 9:1, etc. In these cases, we also refer to these at Transmission Line Transformers (TLT).
