Isn't the entire frequency range that it is capable of transmitting in licensed spectrum?

I doubt you can make it transmit far outside the bands it's designed for. Doubt any of those frequencies are unlicensed...

Aren't there strict limitations on the maximum power output of any radio transmitters? At least in Germany there are quite low levels even for "free" frequency bands, so long-range FPV flight boosters/repeaters are already illegal, although they are working in a free band.
