Another problem with that idea. Many units with 2 antenna ports, including aPP, will transmit on the antenna that it last received the strongest signal. So your backaul antenna received traffic from your NOC. With the aPP set in repeater mode it will rebroadcast the traffic, but on the same antenna it received the traffic on. So it'll just send it right back to your NOC instead of rebroadcasting on the omni. Use seperate radios.
