It is not an approved surface to mount a odu.
I was specifically ONLY referring to the poster I quoted that eluded to stucco itself "being bad, very bad". If you will re-read it, I made no mention to my beliefs of the current install processes; just that there is nothing wrong with stucco itself. However; I do think the installer of this particular job, as well as the home owner, made some bad choices. In another post all I said is that I say is that I as well as numerous others in the area do have them without issue, which is fact and likely fairly normal in the desert SW. Maybe those were done by better installers and maybe before rules about stucco were set in stone; so to speak.
So what's the beef?
