1420, and 1660 are in the L band (1000-2000 MHz)
4.45 is in the C band (4000-8000 MHz)
9.2 is in the X band (8000-12,500 MHz)

The other bands:

P 230-1000 MHz
S 2000-4000 MHz
Ku 12.5-18 GHz
K 18-26.5 GHz
Ka 26.5-40 GHz
Millimeter > 40 GHz

The book I'm referencing is a little old, so these
designations may be somewhat out-of-date.

In any case, they are just labels. There's nothing
magical about any of the ranges, except of course
the water hole, and pi * the hydroxyl freq, and um
e * 1420 MHz, etc. *grin*
