The engineer is referring to this new item in IOS 12.2(15)JA under the Network Interfaces - Radio0x- Settings.
External Antenna Configuration:Enable/Disable
Antenna Gain(dB):(-128 - 128)
What this is for is to specify to a WLSE when it is doing a assisted site survey that you have external antennas attached to the access point and the gain of those antennas.
The WLSE takes that into account when creating the site survey.
If you do not have a WLSE and are not doing assisted site survey there is no need to adjust or enable these settings.
Hopefully this will be documented ASAP in the online help and in the configuration manual.

Charlie
