Maybe. Ever heard of Moonbounce (eme)?
I have a 16-foot dish (4.9m) which can make 5w very loud on 5-GHz! Compared to a 3-foot dish it is 20Log(16/3) = 14.5 dB more gain (28 times as much signal strength).
It moves slow so would not track a LEO at all and only track HEO at the highest part of the orbit where angular rates are slow. It tracks the Moon very nice. I use in on 1296-eme with 125w.
5-GHz eme typically have 50w or more power. Most run TWT's. Some have hundreds of watts!

The good thing is that high power at 5 GHz is expensive, so I doubt anyone will be running too much more than they have to on P4B!
