I setup the AP using radar detect but all 3 radios in the AP show up on the same channel. Since this is going to be our first tri-sector AP that we have done always used Omni's in the past is it ok to let them all be on the same channel? Or should they be on seperated channels?

3 - 120 degree sectors

wlan 1 - 5ghz turbo (for bridge)
wlan 2 - 2427mhz
wlan 3 - 2417mhz
wlan 4 - 2417mhz

Should these be seperated? They are going to be on Rohn 55 tower using Superpass 2.4GHz ISM 14dBi 120 degree Sector Panel Antenna, 3dB Vertical Beamwidth 8°, with a Front to Back Ratio ³ 30dB. Being new to the tri-sector AP we are not sure if they should be seperated or not or should we just let the radios decide with their Radar Detect option what is the best channels?

use different channel, same 2.4ghz itself gives self interference...

Even better is to use non overlapping channels.

Would using the new Atheros chipset feature Radar Detect be good thing to use in an AP like this? It's hard for us on a couple of towers to do non-overlapping because wireless business ap for office have sprung up all over around us and these two towers have alot of noise from others in the area.
