1.There is no standing wave, it is an abstraction. Look at the formula for
reflection coefficient, the only terms are Zf and Zr.

2. The standing wave does not cause IR losses, the losses are because of the
increase of reflected current. We measure that increased reflected current
and from it create a ratio to the forward current and describe it as a
standing wave ratio.

3. To argue which way a ratio goes is pointless.

4. The jump rope example shows the forward and reflected wave only. One may
observe the constructive and destructive resultant waves. One can NOT see a
standing wave, whereas one may be computed from the observations.

5. Set the reflected current equal to the forward current and the field
changes from electrical to magnetic twice a second. A pure observable non
moving standing wave, some call that resonance.

You dig your logical hole ever deeper, Tom. Current that doesn't move
means that dQ/dt equals zero. Hint: current cannot exist without
movement. Even DC current cannot stand still. AC/RF current is even
worse for your illogical premise.
