Impedance matching ratio of a coax balun

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 … WitrynaThis calculator helps you calculate the characteristic impedance of a coaxial cable given its dimensions. This will also provide the time delay the cable provides for a signal and also the capacitance and …

Balun - Wikipedia

WitrynaGuanella’s goal was to develop a balun to match the balanced internal impedance of a push-pull vacuum-tube amplifier of 960 ohms to the unbalanced impedance of a coaxial cable of 60 ohms, a 16:1 ratio. Since Guanella did not have access to the modern nickel-zinc ferrites of today, his goal was never realized. Even today it would be a ...
