I'm ok with that, as long as we realize that we are defining words to
not line up with US usage.  That's fairly normal, but we should be clear
that we are doing it.

Yes.  I (a ham radio operator) would call that a mast, because it isn't
lattice (like Rohn 65).  But it's on the large/strong end of mast, vs a
2" / 5 cm tubing section.  The general public would call that "cell
tower", but then again they would refer to cell antennas bolted onto the
top floor of a building "cell tower" also - for them, it's a functional
term.  But most amateur radio people would call it tower or mast if just
asked "what's that", and almost all that said tower if you then said
"but really, is it a tower or a mast", would say "well, good point, it's
just a mast, but it's on the upper edge of mast ".

I really mean things that have almost no other purpose.  That structure
is also a tourist attraction, and it seems to have been built for that.
So I would not call it antenna_support_structure.

Here's a photo of something near me for TV, with no other purpose (other
than other communication stuff also put on it).

This is definitely antenna_support_structure.

But I don't really expect people to like this proposal.
