Default Voltage feeding a VHF yagi

So current flowing on the coax braid = Current flowing from X to B +

As you probably know, standing waves in distributed
networks modify the conditions. The current "flowing"
from X to B may not be the same amplitude or phase at
X and B. The current "flowing" from Y to B may not be
the same amplitude or phase at Y and B. This is NOT
a DC circuit! So how can any sane person claim that
the common mode current at X is identical to the
common mode current at B?
