[600MRG] 50 vs 75 ohm coax, getting confused

Totally agree.  Adjust the antenna to match 75 ohms... if you want to be almost perfect...as you need to design it for some impedance if you can at that frequency.  The loss at 630M is so low that it probably doesn't matter.  At our power limit you probably will never get a SWR magnification of E or I to exceed the limits of whatever coax you use.  Great band.
