seems a tag that describes different orthogonal properties
according to the mostly used values. Some describe a
structural system (eg. lattice, guyed lattice, tube), others
a shape (e.g. dish, dome), others a structural property
(freestanding), others a material (stone, steel, metal,
concrete). It’s a complete mess, and concealed fits nicely
by adding yet another different kind of property to it ;-)<br>
<br>
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.</blockquote>

<div>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...</div>

A mircowave antenna with a dome looks like this;<br>

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. <br>
<br>
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. <br>
