Just a little mad. Antennas and cable do fail. That's something you need to consider in your fault tolerance. We've seen stuff fail from pac wireless, gabriel, superpass, etc.. The whole price range. We've also seen MTI ones fail when struck by lightning.
As far as sectors go, there is often enough overlap that people may be able to reassociate on the neighboring sector if you can use virtual APs. We frequently do have a backup backhaul; we leave the old gear in place when we do a backhaul upgrade. Separate UPSs would be good too, as those are often the only thing that gives in a high uptime environment.
