Carolina Windom revisited: 4 to 1 balun does nothing to chokeRF ?

Thanks for the NEC output, Cecil.

I showed how to optimize an OCF for a single band, e.g.
40m. If the 50/120 ohm transformer is link coupled, it will
cause a common-mode current node at the transformer on 40m.
Any antenna system can be optimized if one knows what they
are doing.

For instance, a shunt 1000 pf cap at the twinlead to coax
junction will optimize a G5RV for 75m.
