Understood, Cecil, but when the SWR losses are of so little concern
then the SWR consistency becomes likewise, at least IMHO

Hi Irv, Excellent point! Although I am sure Cecil put it in there as
Point/Counterpoint.

If the SWR on 300 ohm twinlead is 5:1, the impedance at the current
maximum point is 60 ohms. If the SWR on 300 ohm line is 20:1, the
impedance at the current maximum point is 150 ohms (3:1 SWR).

If the SWR on 600 ohm line is 10:1, the impedance at the current
maximum point is 60 ohms NO MATTER WHAT THE ANTENNA IMPEDANCE.
The impedance at the current maximum point for a 6000 ohm antenna
fed with 600 ohm line is the same as the impedance at the current
maximum point for a 60 ohm antenna fed with 600 ohm line. That's
a definite '+' in my book. I like 60 ohms better than 150 ohms.
