I havn't much idea on what the present argument is all about. And I
have no wish to take sides. But - If Line-1 has impedance Zo1 and is a fractional wavelength L1 long, and Line-2 has impedance Zo2 and is a fractional wavelength L2 long, then when both lines are connected together and are brought into so-called 1/4-wave resonance by pruning the length of one of the lines, it is IMPOSSIBLE for L1 + L2 to equal 1/4-wavelength or 90 degrees. There are ALWAYS some degrees "missing" - depending on the ratio Zo1/Zo2. Except only when Zo1 = Zo2 will L1 + L2 total 90 degrees. Can be proved mathematically without invoking standing or reflected waves. You just have to believe in mathematics. Line-1, of course, is a loading coil and Line-2 is a whip. I hope this settles an argument. For a demonstration download program TWOLINES from website below. ---- .................................................. ..........
