Honestly, I doubt the quality of a 120 degree sector that will give you 180 degree coverage. I would hope your at -6dB or -8dB at that point.
For instance... check out this sector... its -6dB off at 180 degrees http://www.mtiwe.com/uploads/product/127.pdf So your 12dBi sector is now a 6dBi sector...
