While I understand what these are (when I was 10 years old, I strung up a 12-meter shortwave antenna wire on our roof with my dad), I haven't mapped into OSM these kinds of antennas, exactly.  However, I have mapped "guy wires" on a very tall television antenna (KSBW-TV, Channel 8, Salinas, California) [1] — wow, that edit was NINE YEARS AGO — believing (for exactly the same reason) that these were a "flight hazard."  The antenna — along with others in this area — IS (are) marked on aeronautical charts.

I agree that power lines aren't correct in the case you cite, but the guy wires I mapped [2] actually don't have an "active" tag:  they only have a note=* tag, the value of which is "Guy wires?  This is a very tall tower."  If there were a tag wiki-documented, I would have used it, but I wasn't sure what might be the right tag to "coin."  As I'm a more bold mapper a decade later, I might choose man_made=guy_wires, as man_made=tower (communications_tower...) is the "tagging family" of such structures.  Similarly, in this case, one might choose man_made=antenna_lines_VLF (or something similar).
