| Using this tag is discouraged, use man_made=antenna instead. |

The reason is documented in Deprecated features. You are still free to continue to use or interpret this tag as you see fit since OpenStreetMap does not have “banned features”.
Under no circumstances should you (semi-)automatically change “deprecated” tags to something else in the database on a large scale without conforming to the automated edits code of conduct. Any such change will be reverted.
The key power=* is for electrical power distribution, not mapping of large antennas. Use man_made=antenna.
An antenna wire is a wire of an antenna spun between at least two support structures. Such wires can be found at some transmitters working on frequencies below 30 MHz.
How to Map
Draw a way and add the power=antenna_line to it. The towers that support the power line can be mapped using man_made=tower or man_made=mast. It is not necessary to tag antenna lines with a layer=* unless two antenna wires cross over each other.
Tagging
It is also possible to give some additional and advanced information about antenna lines :
- The number of wires=* per conductor.
- You may look at cables=* for the number of wires the antenna line is composed of.
| Key | Value | Comment | Recommendation |
|---|---|---|---|
| power | antenna_line | It's an antenna line, normally mapped as a . | mandatory |
| voltage | <operating voltage> | The voltage on the antenna line | recommended |
| operator | <cable operator> | The name of the company which operates the transmitter to which the antenna line belongs | recommended |
| cables | <number of cables> | The number of cables for this section of antenna line | recommended |
| type | <type> | Type of wire antenna. Typical are "Collinear antenna array" and "Curtain array" for shortwave antennas, while wire antennas for VLF/LF/MF are just wires | recommended |
| wires | <wire bundle per conductor> | The bundle form factor for each conductor of the antenna line | optional |
| frequency | <operating frequency> | The frequency given in Hertz at which the transmitter using the antenna line is operating | optional |
| name | <name> | The name of the transmitter using this antenna line | optional |
| ref | <reference> | The reference of this antenna line section | optional |
Since antenna lines aren't insulated, they can only be located overhead to protect them from grounding with external elements.

Note
Overhead feeder lines of transmitters are mapped with power=minor_line and the corresponding attributes.
