Default antenna physics question

The phrase "80% antenna efficiency"
contains both a unitless number and dimensional metadata.


Actually, it doesn't - you are filling in the blanks with presumption.
Given that "efficiency" has been hijacked, the phrase above could as
easily relate to wind load.


Precisely why metadata is so important to describe data.


So, by this you agree that your original metadata was not useful. As
for it being "dimensional" there was nothing dimensional expressed nor
offered by you afterward in further elaboration.

The whole purpose of data analysis is to aid in effective decision
making.


Metadata is useful in Figure of Merit and such is the entirety of your
argument.

Unfortunately, the only thing revealed here is that your metadata is a
portmanteau word covering an infinite regression of refining
statements. We would be better served in consideration of the Figure
of Merit side of the discussion where many could easily discard a lot
of metadata deadwood.

That is the practice of engineering.

Compounding unfortune, Art is incapable of providing weighted values
to make progress in any discussion. There is no Figure of Merit
consideration, there is only the combinatorial explosion of
possibilities. That has lead us through the dimensions of 180 meter
wavelengths to the sub nanometer relativistic effects of nuclear
physics - all treated with equal importance such that practicality has
been debased.

This is the Art of science fiction, metaphysics, or religion.
