Be sure to distinguish the differences between Effective Radiated Power versus the Loss - for in some instances (as a general guide not meant to insult anyone) a dummy load can be considered 100% Efficient - but as only SWR is to losses as Resonance is to Length.

You can't use a dummy load as efficiently as an antenna (e.g. - ERP) - as also (compared to) the analogy of the Resonant Length - when you increase the frequency used on the Resonant Length, as you get closer to multiple fractions of wavelength. The appearance of the antenna changes from one set of values - to another - which increases GAIN as a factor of dB - but not in the sense of power - but as power DIRECTED into a pattern increasing the Effective Radiate Power.

You can also increase the Resonate Length of antenna - make it LONGER into those fractional wavelengths - and obtain those same lobed patterns which help provide a form of gain, not as a power - but as a radiative pattern of change.

So, to claim matching as a loss, I don't see it that way, it only becomes a loss if the Gain in pattern (or capture if that would be the word) can't offset the coupling losses the antenna has as an impact to the system - the system being the whole mess strung up and connected to the transmitter.

You mentioned the 6-in coil pipe antenna - knowing someone who has used one - I did find it rather hilarious to use such an antenna - but in its ability to be turned and aimed - makes such a device rather useful to "cut the mustard" when it came to having local QSO's
