Length of Coax Balun
The original voltage wave and the same voltage wave with 180 degree are in antiphase. This means destructive interference, and we have zero Volts? Combine a voltage wave with itself with 360 degree and the amplitudes add, so from V we get 2*V?
See...
Can you explain why this is the case volker?
Why does a 1/2 lambda line work? Maybe because this way the reflected wave we want to avoid gets wiped out by itself?
If so, would this imply that every n*1/2 lambda line with would work? Is this correct?
"Wiping reflected wave out" feels stragen...
Hello,
I am building a 2.4 GHz Yagi-Uda directional antenna for Wifi. I use a RG-58/U coaxial cable with 50 Ohm. I use the Yagi calculator of VK5DJ as a guide: https://www.vk5dj.com/yagi.html
The folded dipole has an impedance of 288 Ohm. The transmission line has an impedance of 50 Ohm. The...
