Impedance matching ratio of a coax balun
Witryna15 cze 2012 · Most simple coaxial balun is the 1:4 balun, and then is it the 1:1 balun you have found. I'll try to explain: Zsource 50 Ohm is split in two coxial arms. If both … WitrynaThe antenna impedance matching components (BOX “Z” above) to match the antenna impedance to the coax line impedance (usually 50 ohms). For non-resonant end fed antennas, the typical feed point impedance is 300 to 600 ohms and a 9:1 impedance transformer (e.g. 450 ohm average antenna impedance to 50 ohm coax, also know …
