well we are using narrowband filters of 10Mhz for each of our RFHeads, the issue we have is we don't have room for 2 sectors per direction so i'm trying to find a way to use a custom dualband andtenna on 3.5/3.5 or perhaps just a 3.5ghz 4x4 mimo antenna so 1 carrier on X and one on + with say channel 3515 and 3415 or something like that.
