Herelink Air Unit Antenna frequency range

I would like to find out more about the frequency range of the Herelink Air Unit Antenna. Is the antenna a 2.4 GHz antenna or is the antenna a 5G/4G antenna?

2.4 GHz antenna,5G is for controller upgrade only.

What do you mean by controller upgrade? The herelink controller has no cellular capability, right ?

I mean firmware upgrade.

Thanks for the information
