Is buysing external antenna required for AIR-AP1230A & B?
I just went through the configuration checker for a Cisco Aironet AP1230A-A-K9 and then for a AP1230B-A-K9. Both checked out the config as OK, but had a warning about Wireless product antennas. I'm hoping this means that an antenna is optional, but if I buy an antenna, the only officially supported ones are the ones listed here:

Are you asking "Can the radios be damaged if they are operated without the antennas attached?"
If yes then some radio equipment manufacturers specifically warn against doing this because it will damage the transmitter. Most pieces of amateur or commercial radio equipment carry this warning because they operate at a much higher transmitter power. The reflected wave standing wave ratio (SWR) caused by a lack of a proper antenna or load can damage the final amplifier stage known as the power amplifier (PA).
