It’s a complete mess, and concealed fits nicely by adding yet
another different kind of property to it ;-)
I think dish and dome are for the antenna. A dome would be a cover
to keep stuff out of the real antenna surface - usually a dish.
Right, what I meant was that something can be a freestanding lattice
tower and made of metal. Or a dome covered guyed lattice tower.
Usually the same key should describe the same property, not sometimes
a material, sometimes a structural system and sometimes the cover of
an antenna...
A mircowave antenna with a dome looks like this;

If mappers are using the tags for a tower to describe the antenna then
they are 'doing it wrong' as the tags for the tower should describe the
tower, to describe the antenna they should use tags for the antenna.
I don not understand what a "a dome covered guyed lattice tower" is.
Could be a lattice tower inside a large dome? In which case I would
expect the dome to be one feature and the tower another feature inside
OSM, there would be no need to tag the tower with the dome as that would
be redundant.
