External antenna gain is factored into the maximum transmit power of the access point. Antenna gain is an indicator of how well an antenna focuses RF energy in a preferred direction. Antenna gain is expressed in dBi (the ratio of the power radiated by the antenna in a specific direction to the power radiated in that direction by an isotropic antenna fed by the same transmitter). Antenna manufacturers normally specify the antenna gain for each antenna they manufacture.
Impact of incorrectly settings Antenna gain.
You might see a decrease in transmit power output.
What I was told about this is that if the gain is set too high, the algorithm will adjust the TX power so that you will not go beyond the regulation of the country the wlc is set to. So if the current EIRP is below the maximum for the country code, it will not have any effect.
If your using external antennas, then yes you should set it. Now if I have a mix of 3602e and 3602i, but the gain on the external antennas are the same gain or real close, then I don't bother changing the gain, but that's me. I have not had any issues. Now if I'm using a higher gain antenna like a 6db or more, then yes.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.
