6-7GHz Dual-Pol Horns?

With the announcement of split-sector mode being added to ePMP4600 4x4 APs, the idea of using horns for split sectors on light duty towers becomes very attractive. Does anyone know of manufacturers that make horns 6-7GHz 2x2 ? I dont see any in 6GHz from RF Elements and KP Performance seems to only go up to 6.4GHz. Any recommendations are welcome!

Thanks!
