Muon GNSS antenna: is it powered?

Firmware Libraries
1

The library particle-som-gnss has the following lines:

LocationConfiguration config;
config.enableAntennaPower(GNSS_ANT_PWR);

Is the Muon antenna powered or what does the above command do at hardware level?
Once getting a fix can I disable the power to it without harm?
Thanks

The M-SoM supports an active antenna, powered by a supply controlled by that pin. If you are using a passive antenna, you don't need to power it. If you are using an active antenna, you should keep it powered whenever you are using the GNSS. The current used by the antenna is typically very small.

Ok, I'm using the antenna that comes with the Muon which I believe is a passive one, so I'll leave this powered off.
Thanks!
