Hi,Sir

Steps to enable 3rd radio for coverage on controller:
AC(config)#ap-config 740
AC(config-ap)#extra-coverage enable

Verification:
Telnet to designated AP740, and check whether the AP is broadcasting SSID with radio3
740#sh dot11 mbssid  

or you can exec" show ap-config summary" to verify whether have STAs connect to 3rd radio
