Godfrey: To give you a direct answer to your question. Size !  Years past
all radar systems were 60 Hz. To pull a main power supply rack out it took 3
men just to put it in the isle. Air craft radar uses 400 Hz.  Using high
frequency power you reduce the cost, wieght, and size by a factor of 10.
Some aircraft systems now use 1600Hz to further reduce size and weight.
