My old club has a Ubitquiti Air OS 5ghz dish with a Rocket M5 XW on it. It is still in its original factory firmware. They want to convert it to AREDN. Is this dish compatible with AREDN? I don't see a specific Air OS model on the compatible device list. But since it uses a Rocket M5 XW i thinking it is.

AREDN firmware replaces factory firmware in supported routers.
Antennas do not have firmware.
Antennas have bandwidth operating ranges.
Passive reflectors do not have firmware.
Dish style reflectors have large bandwidth operating ranges.
The Ubiquiti Rocket M5 XW is a combination router, radio, and antenna.
I hope this helps,
Chuck
