You really should not have any problem with dish installation as long as dish is pretty secure. They are not that heavy.

Best advice would be to tell the dish installer to install it so it will be easy accessible by the user. Or better yet, to put pn ground on a poll. This way if dish get out of alignment (which really shouldn’t if it is secure), the home owner themselves can realign it with a pair of pliers.

Receiver comes with a signal strength meter, and if get out of alignment, you can pretty much get it back in position with out calling out an installer. But as long as it is tightly secures, you shouldn’t have any problem with wind damage or realignment issues.

I installed my own dish and may be after three years, only had to realign it once and that was due to an ice storm. Also make sure your installer ground the dish.

Good luck.
