OpenWrt with sector antenna

Hi there

Is there any additional configuration for antenna gain should I use it if I install high gain antenna like 19db 120 degree sector ?
And is there any limit with antenna gain in openwrt ?


You can only use what the driver provides/allows. That is usually that what is allowed in your Region/Region set in OpenWrt. More than adjusting transmit power to the allowed maximum cannot be done without driver hacking (if possible at all).
