WiFi as WAN

I have a pepwave max transit, with a pepwave one mini ap, with a pepwave 42G antenna on the roof (with all 7 antenna cables connected to the router).

When connecting a device (hotspot) over ‘WIFI as WAN’ to the pepwave router – is the hotspot communicating through my pepwave one mini ap or the pepwave 42G antenna?

WiFi WAN on the Transit uses its WiFi Radio so its connected via the 42G antenna.
