That might be true if the final element in the array is exactly matched
to a load. If the element is lossless and perfectly mismatched, i.e. its
load is a short-circuit, 100% of its received energy can be reradiated.

I choose to respond to Art on this thread and not to start another to
contradict his prior art.
