This is a way to solve most of the problem, but it fails the "map it
as I
see it" test.
man_made=antenna + antenna:reflector=dish does map the satellite
communications antenna I just spotted... But what the naïve mapper I am
really wants is man_made=antenna + antenna=dish (or
monopole/dipole/yagi/helical/phased_array ...) : "map it as I see it" !
Then one can add antenna:propagation, antenna:application,
antenna:propagation, antenna:polarisation etc. but they are accessory.
Am I mistaken in believing that the main tags chain should focus on
offering a straightforward way to map the apparent physical features,
rather than invisible distinctions ? Not that invisible distinctions
are
not welcome too - but they should stay out of the way.
Sympathies!
An alternative is available ...
man_made=antenna
dish=yes
So far, so good.
cross_gain_feed=yes
What does that mean? I'm a licensed radio amateur (/for more than 30
years/) and I never heard of that term... :-/
Arr casse grain ... apologies. (added word to spell checker)
How is the reflecting dish signal connected? There must be a real
antenna that does that.
And then there is the way the antenna gets the reflected signal.

There is a lot to learn, we should have more life times ...
two_way=yes
Prove that!
As an example: This may be a TV studio where TV programs are transmitted
to a satellite for distribution.
As a TV studio it may also receive TV signals from remote broadcasts...
or other TV studios connected to the satellite.
OSM accepts 'knowledge' as a suitable source of information.
satellite=yes
Prove that! Because it points at the sky? There are many other good
reasons to point an antenna at the sky...
Again? If you don't know .. don't tag it. But don't deny others from
adding stuff they do know.
Don't know that a road is closed in winter? then don't tag it.
Know that a road is closed in winter - tag it.
Come across an open road in summer that is tagged closed in winter ...
and you want to verify the closure? Come back in winter or contact the
relevant mapper.
The most common antenna people see are TV antennas, most pople know what
they are and can tag them at least the basics. Next would be mobile
phone antennas. After that they are not so well known, most would have
to look them up to find out what they are.
