Card purchased on LEM swap list, installed per User Guide
instructions, antenna connected. System profiler does not detect it,
and there is no Airport option in Network control panel.

Hardware Overview:

Model Name: Power Mac G4
Model Identifier: PowerMac3,6
Processor Name: PowerPC G4 (3.3)
Processor Speed: 1.25 GHz
Number Of CPUs: 2
L2 Cache (per CPU): 256 KB
L3 Cache (per CPU): 2 MB
Memory: 2 GB
Bus Speed: 167 MHz
Boot ROM Version: 4.4.8f2
Serial Number (system): XB40905UQ6P
Hardware UUID: 00000000-0000-1000-8000-000A95CFC548

OS is 10.5.8.

Is an Airport base station necessary for the Airport card to be
detected? I do not yet have one.

Airport is simply Apple's registered trademark for its implementation of
the internationally standardized 802.11.

There are at least four variations: 802.11a, 802.11b, 802.11g and 802.11n.

802.11a is so very old that most later cards support only 802.11b and
802.11g, the so-called 802.11b/g cards.

The newest card also supports 802.11n.

However, when Broadcom redesigned its card for 802.11n, it made it an
802.11a/b/g/n card.

I believe the earliest airport cards, the ones which are a "shortie"
PCMCIA card, are 802.11a, only, and that is probably why one might think
these can only work with an Apple Airport "access point", as by that time,
everyone (Cisco, and a great many others) had already moved beyond 802.11a
and were supporting 802.11b and 802.11n, but NOT 802.11a.

802.11a is a poor design, which is undoubtedly why later "adopters"
eschewed Apple's preferred 802.11a, and went immediately with 802.11b or b
and n.

Most WiFi USB dongles are 802.11b/n, and some of these are so highly
integrated that these can be made using only one LSI chip (Realtek),
whereas before, these required at least two chips (protocol chip and a
transmitter/receiver chip, as in the formerly ubiquitous ZyDas products).

Absolutely not, I have several computers with various Airport cards and they worked long before I had an Airport Base Station.

Try reseating the card. Make sure it's in the right way.

What Clark said, these are hard to seat sometimes.

The earliest Airport cards are "b" only. I don't recall ever hearing of Apple offering a card that supported "a".

In general, (meaning Airport and non-Airport) cards support "b", newer ones support "b" & "g", and even newer ones also support "b", "g" & "n". Some third party cards also support "a".

No, Apple never shipped an A-only card, they were always A+B cards (they were internally identical to the Lucent Orinoco Silver cards, which were what early Airport base stations actually used.)

Also most, if not all WiFi routers at the time also supported A and B. I know the Cisco ones we set up in our building (which were contemporaneous with the advent of the Airport) supported both A and B. You could get amazing speed from A… IF you were within, say 15-25 feet, completely unobstructed, of the router.
