This is a way to solve most of the problem, but it fails the
"map it as I <br>
see it" test. <br>
<br>
man_made=antenna + antenna:reflector=dish does map the
satellite <br>
communications antenna I just spotted... But what the naïve
mapper I am <br>
really wants is man_made=antenna + antenna=dish (or <br>
monopole/dipole/yagi/helical/phased_array ...) : "map it as I
see it" ! <br>
<br>
Then one can add antenna:propagation, antenna:application, <br>
antenna:propagation, antenna:polarisation etc. but they are
accessory. <br>
<br>
Am I mistaken in believing that the main tags chain should
focus on <br>
offering a straightforward way to map the apparent physical
features, <br>
rather than invisible distinctions ? Not that invisible
distinctions are <br>
not welcome too - but they should stay out of the way. <br>

Sympathies! <br>

An alternative is available ... <br>
<br>
man_made=antenna <br>
<br>
dish=yes <br>

<p>What does that mean? I'm a licensed radio amateur (<i>for more

Arr casse grain ... apologies. (added word to spell checker) <br>
<br>
How is the reflecting dish signal connected? There must be a real
antenna that does that. <br>
And then there is the way the antenna gets the reflected signal. <br>

<p>Prove that!</p>

As an example: This may be a TV studio where TV programs are
transmitted to a satellite for distribution. <br>
As a TV studio it may also receive TV signals from remote
broadcasts... or other TV studios connected to the satellite. <br>
<br>
OSM accepts 'knowledge' as a suitable source of information. <br>

<p>Prove that! Because it points at the sky? There are many other
good reasons to point an antenna at the sky...<br>

Again? If you don't know .. don't tag it. But don't deny others from
adding stuff they do know.<br>
<br>
Don't know that a road is closed in winter? then don't tag it.<br>
Know that a road is closed in winter - tag it.<br>
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. <br>
<br>
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. <br>
