<br>
I have updated with some more stuff. A fair proportion from your
post - comments below. <br>
Wifi sucks as a tag .. it is a system not a use. Rats. Need a
value for it. <br>

<p>Hello, Warin,</p>
<p>a couple of quick, non-exhaustive, notes on antenna use (or is
it <i>usage</i>?) even if I'm still doubtful we should map with
such detail:</p>
<ul>
<li>amateur_radio: antenna systems used by <b>licensed </b>radio
amateurs</li>
</ul>
</blockquote>
<br>
A mapper will not be able to tell if they are licensed. So I would
not stipulate it. And this is tagging the use, not who uses it
(operator=licensed radio amateur?). <br>

<ul>
<li>transponder: I think they are mostly used on <b>mobile </b>systems
(<i>unmappable...</i>). Is there any fixed transponder? What
used for? Probably just very few fixed AIS station. Make it
specific, use=AIS (as wifi is specific compared to the generic
"digital communication")</li>
</ul>
</blockquote>
There may be some fixed transponders to identify hazards and enable
checking. Possibly these are known by there systems name rather than
there use(age). I'll have to check. Arr a OSMwiki example

Yes. There is a wikipedia link on it. But I'll change the text.<br>

</ul>
</blockquote>
The ones I am thinking of are 300mm diameter and about 2 kg. They
have choke rings around them. <br>
Some of these are used to provide compensation to the local GPS
equipment. <br>
Humm there will be some use to describe the correction .. WASS if I
recall correctly. <br>
<br>
The other very much larger GPS ones to do the control functions ..
there will be very few of them around. <br>
<br>
I think 'we' should include the other 'GPS' systems here too. <br>
Possibly a better description will be GNSS - global navigation
satellite system.<br>

Yes . possible. <br>
Don't think LORAN is used any more. <br>
VOR looks to be halved due to GPS use. <br>
I'll include them with a note about reducing numbers due to GPS
adoption. <br>

No to the above 2 .. I think those are systems .. not uses? <br>

ELF etc are frequency ranges - spectrums .. not uses. We know what
frequencies broadcast radios and televisions are so those can be
mapped. The key frequency=* can have a value that is a range. <br>
The spectrum could also be tagged ... using the wavelength rather
than the band name. Or do you think a tag for the band name is
needed? I don't think it is. <br>
<br>
Some things are 'classified' and most people won't map that
information. <br>

Yes. Some places are paranoid. Does not stop outside foreigners
mapping same. Most of them probably don't know the local attitudes.<br>

Following from my previous post on antenna:type .. <br>
<br>
<br>
This is the first of the antenna:* keys that could be used to
categorise various 'types' of antennas. <br>
<br>

<br>
This one is on the use to which the antenna signal is put. <br>
<br>
<br>
It does need input on the values. And anything else of concern
naturally. <br>
