My example is relevant without the need of the Bird wattmeter.  I fully accept the fact that the directional coupler samples RF
voltage.  I'll respond to you as I did with Steve.  Namely, in the absence of a load on a loss-less line, any and all reflected
power is being absorbed by the fixed-impedance source (i.e., broadband PA).

If reflected power is not absorbed by the source, where is absorbed?
