It's good that radio telescopes have been mentioned. While considering
this issue, you should also take a look at towers with
tower:type=communication and tower:construction=dish
I'm not sure if it is sensible to tag a large satellite dish as a
"tower" but that is currently an option that has been used
occasionally.
I'm also aware that a common recommendation is to tag them as towers,
but I would not see this as a good option, for "big/high structures"
we could have a basic distinction already in the main tag (and these
tags are also already used), e.g. cooling_tower, chimney, dish,
lighthouse, bell_tower, water_tower, flagpole etc. rather than
cramming everything into a big "pre-category", which isn't useful on
its own anymore because of the very broad scope.
If a tower is a structure that is higher than wide, some dishes could
fall out. If you require a tower is a structure where people can go
into or atop, a requirement that isn't currently set but isn't
completely unreasonable either, dishes would also be excluded.
A tower of a mast could be used for lighting, or an antenna. Or flags,
or a signal lamp ...

The tag mast or tower should not be assumed to indicate the presence of
another feature.
OSM guide - one feature = one OSM entry.
So tag the mast/tower.. then add another entry for the antenna (or other
feature).
