I'm recently trying to build a dual-segment Yagi antenna for UV frequencies, and I've watched many video tutorials online. However, I still can't figure out how to properly connect the feedline, so I'm asking for help from experienced ham radio operators:
Currently, my understanding of the connection method between feedline and antenna is that "the feedline, a balun (such as a coil), and the center conductor are connected to two separate lines, which are then connected to the opposite interfaces of the excitation oscillator."
For antennas operating on a single frequency band for U or V, this is straightforward because there's only one exciter and you simply connect the corresponding wire to it. However, when dealing with UV dual-band antennas, the situation becomes more complex due to the presence of two exciters with different lengths and significant differences. This results in needing to connect 2 wires to 4 exciter ports. I'm unsure how to properly connect the exciters to the feedline. My intuition tells me that I should perhaps connect them like this:
However, in reality – as evidenced by the videos I've seen – it's not connected this way.
I would like to ask for advice from experienced individuals on how to correctly connect the feedline to a Yagi-Uda antenna with UV double segments in practical situations.
Thank you very much!
