As some folk have said, the pulse power can be higher but average power
kept low. I guess that there is a trade off with a lower pulse repetition
frequency to reduce average power.. or is the rotational frequency reduced
to compensate.. ?

The pulse rep rate and rotation speed are probably going to be about the
same in the 2KW and 4KW radome units. The power consumption doesn't scale
with the pulse power because most of the power is used in the drive motor,
processing electronics, magnetron filament, etc -- stuff which draws about
the same amount regardless of the transmit power, or at least not 2x the
power. The transmit pulses are of such low duty-cycle that they don't
contribute that much to the total power consumption.

If there is a major difference in power drain, it is probably due to other
design features.
