It's impossible to tell from looking at it in a photo taken from that distance what band a parabolic aimed (pan/tilt motorized) geostationary satellite antenna of that type is. Unless you're close enough to measure the diameter of the feed horn. Small size means it's unlikely to be C-band as not enough gain unless you want to waste a huge section of transponder space at BPSK modulation and ultra low bps/Hz ratio. It could be X, Ku, high Ku, Ka, etc.

Also extremely likely a craft like that has L/S-band more omnidirectional low data rate command and control radio talking to something in orbit. Basically same idea as L/S-band Inmarsat but operated on military satellites. Obviously the Chinese government won't be using Iridium.

Somewhere I think there are also some laid off ex Google Loon project engineers who are having a good laugh about this whole thing.
