Yes, im running 2-RFE 90 degree 4x4 horns. I dont have it in split sector anymore, however it is supported. Mine is deployed with all horns pointed the same direction covering 90 degrees. If you do the split sector, make sure its wired up properly. Its antenna 1-0/1/4/5 antenna 2-2/3/6/7.
There are still a couple things that are being worked on, but so far it seems to work really well. Im still experiencing a random AP lockup that requires a reboot to restablish the SMs, but i think my case is kinda rare and is being worked on internally by Fedor and Chinmay.
The only “negative” i can say in regards to the setup is there is something wrong with the signal levels. Ive got several other 90 degree horns out with other equipment and around 6-7 miles im usually around a 68-70 signal wise. With this setup around 4-4.5 miles will yield the same signal levels. Much beyond 5.5-6 isnt possible.
Besides that, id say go for it! It works pretty good and the development of the product is definitely headed in the right direction. Most of my “complaints” are just being nit-picky trying to make sure the full picture is understood. Theres nothing that is a show stopper, put it out and enjoy
