|Definition:||The application of an antenna’s signal.|
Add the property key antenna:application to indicate the application of an antenna.
To indicate the application of an antenna’s signal is put, e.g. radar
There is use of antenna:type=* in the data base. The values used describe various things about the antenna, it polarisation, use, configuration, etc. This leads to a mess. See Taginfo antenna:type#values
Better to have separate tags for each feature of the antenna so they are separate and constantly tagged.
A proposed collection of tags is;
- antenna:application = mobile_phone/broadcast_radio/broadcast_television/citizens_band/amateur_radio/radar/* to state the application of an antenna’s signal is put.
- antenna:propagation =reception/transmission/two_way to denote the direction of the signal.
- antenna:configuration = monopole/dipole/yagi/log_periodic/horn/curtain/helical/phased_array/loop/* To state the antenna configuration.
- antenna:polarisation = vertical/horizontal/dual/circular/* to denote the signal polarisation.
- antenna:reflector = dish/wire_element/wire_screen/* To state the antennas reflector – if it has one.
- antenna:cover = radome/* To state the antennas protective cover – if it has one.
The values for discussion so far are;
|Amateur radio covers a wide range of antennas and will need some knowledge to map appropriately.|
|Behörden und Organisationen mit Sicherheitsaufgaben. German government secure radio network.|
|An audio signal, in common use with different technologies of AM, FM and Dab. Transmitting antenna shown.|
|Commonly called TV. An audio visual signal, in common use. Some common receiving antennas shown.|
|Commonly called CB. A two way radio system, usually unlicensed.|
|communication||This describes most the applications of an antenna. Please replace with a more descriptive specific tag.|
|Long range navigation system, uses base stations with large antennas.|
|There is a choice to be made between values of mobile phone, cell phone or cellular phone. Most people probably use mobile_phone to describe the use so OSM may well chose to use that. Looks popular on taginfo.|
|A reflector - like a mirror but for radio frequencies. For an active repeater see below 'repeater'.||150px|
|RAdio Detection And Ranging, a relative location finding system. The abbreviation is in common use even in languages other than English so there should be no need to tag the unabbreviated version into OSM.|
|Repeaters are used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction. Usually the repeater retransmits on another frequency to stop interference. There can be a number of these to form a chain over long distances. For a passive repeater see above 'passive_repeater'.|
|Examples of a 'global navigation satellite system' are the American GPS or the Russian GLONASS.
A fixed GNSS antenna. Maybe used for correction determination for local corrections to GNSS readings.
|Used for satellite communications, domestically for TV and internet particularly in remote locations.|
|Responds to an incoming signal by transmitting an outgoing signal. The outgoing signal usually contains information to identify the repeater.|
|A system used for aircraft navigational purposes. Caution VOR is an abbreviation of Very High Frequency (VHF) Omni-Directional Range, but that is a bit long! I think vor may be acceptable rather then the full length?|
|A digital signal used for many purposes.|
|*||For things that have not been thought of!|
Where another feature inherently uses an antenna then the application of the antenna is usually implied e.g. a radio telescope will have an antenna but the application is clearly as a radio telescope.
