you can do it when it makes physical sense. it does not make sense in
standing waves for all the obvious reasons that i have pointed out. it
does make sense in the individual traveling waves. just accept what your
little swr meter tells you, it shows the forward power and reflected
power, that is all you need and the only powers that make sense.


Little SWR meter shows forward AND reflected power in one direction, and
reflected power only in reverse direction. Why is the Bird wattmeter
calibrated in Watts, measuring power (forward and reverse) and has chart to
calculate SWR, when there are no standing waves and no power in them?
Laying waves or sitting waves???

Seems to me that the PROBLEM is that some consider standing wave to be some
imaginary, stopped, frozen wave, no good, while some of us consider standing
wave to be the result of superposition of forward and reverse waves, that
can be (their components) measured, current heats when flowing through
resistance, voltage "burns" when poor dielectric.
Like there is standing wave current, but no standing wave, huh????
Or are we forgetting that we are dealing with electromagnetic waves?
Can someone sort out the terminology and definitions?

Hi, Yuri,
Cecil and Dave aren't taking resistance into account when they
talk about waves. In other words, they're not writing about real
transmission lines, coils, and such. The only lines they care about are
the ones in their minds: the simple ones where the attenuation constants
are always zero, and current and voltage are always either in phase, or
90 degrees out of phase, and there is never any dielectric breakdown, no
matter the voltage. You can only feel sorry for guys like that.
