Yes... Internal antennas have a set gain and antenna pattern. The antenna gain command does not affect the radios. It is used for information only if using WLSE/WCS/NCS or Prime.

The gain is basically for the antenna used on the access point. An 1142 has built-in antennas so this command will not change anything. On access points that have external antennas, you can change the gain to what the gain of the antenna is rated for. This changes the total EIRP of the AP.

Hi, Scott

Ok, rather internal antennas clearly, but what "In Use 8" means? Does it means, that internal antenna have preconfigured Antenna gain (by default) and the Direction pattern has a little changed form?
