If this subthread is about transmission lines and matching, I think you need to 'think outside of the box' a bit more
In a practical tranmitter station setup, where Hams compete against each other to be the strongest with same input power limited by law, they have to find ways around problems, like obtaining a wide frequency range where there's narrow band components (i.e. antenna) that can't be adjusted easily.
One 'problem' is the keeping the transmitter output, feeder and the antenna matched for best power transfer. The problem is with a "matched antenna/line/transmitter", is that a large and fixed HF antenna can only be made to size for a narrow band of frequency, and that operating outside of this range there's so much mismatch, that only a fraction of the allocated band is available. So a station would have to pick a 'slot' and hope others chose the same slot.
The solution to the problem of covering the whole band, with all of the power, is
don't try and match anything with the feeder/transmission line at all. Construct an antenna feeder which has some arbitrary Zo doesn't matter too much, but nevertheless relatively constant along length. It'll be two parallel conductors separated by air, with spacers holding the wires apart. No attempt to match the antenna to this feeder either. Then instead of the transmitter having 50 ohm output, it has a variable real and 'imaginary' impedance. The imaginary impedances are set to annilhlate/cancel eachother.
The transmitter real impedance is set for maximum RF field strength from the antenna, in practice it won't be the same as the antenna's real impedance, because the grossly-mismatched transmission line feeder will modify the impedance from one end to the other.
