AN (Army / Navy) Component Designators & Designations
This is a very comprehensive list of U.S. (Army / Navy) AN Components Designators & Designations
These AN (Army/Navy) component designators describe nomenclature that sometimes replaces the AN part of the
designator.
For example, ID -42/APQ-13 describes an airborne, radar, special purpose (APQ-13) with a model
42 indicator (ID).

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
