Your answer just shows how much you know about installing dishes. I live in the country and had a 18" dish mounted on my facia for 8 years with no problem. As I said before excuses are like a--holes everyone has got one. When you have done 4 or 5 thousand installs you can instruct me on proper installation techniques. Your install is neat but it is not done properly try to do each install the way you would want it on your house. Would you want the dish on the front of you house?
