It depends on the type of quality control (QC) you are talking about.
The good type of QC examines the installation and verifies that all items are installed correctly and that the total system has a good chance of giving dependable service. They also monitor the performance of the installer for both the technical details and customer relationships. Someone will have to bring the installation up to a reasonable standard.
The other type of QC is fraud being perpetrated by the installation company. These QC techs are part of a team that works to avoid paying the installer for the installation. When you combine an unrealistic work load with dispersed routing and equipment shortages it is not hard top find details in the installation that are not technically correct. This produces a justification for withholding some or all of the money from the installer.
Even after the installation is complete they have ways of deducting compensation.
Directv has been too far removed from the installation process to know or care. If you pay your first and subsequent bills you are a happy customer. And you don't care either. You got a FREE installation and the tech is gone.
I have seen good installs and bad ones....even funny ones...but don't recall "tricky" installations.

You know I never thought about that Joe, but what you say makes sense. I guess it really depends on the motive of the QC guy.
I guess I should explain more about the "tricky" part. Basically there were two issues the 1st installer was worried about. 1: The ground rod is on the opposite end of my house to where the dish needs to be mounted and 2: the slope of my room is very steep and he stated several times the dish could not be mounted over a living space.
The QC guy said it was no problem to run a ground to the other end of my house and suggested it would be in the gutter to keep it hidden. House is about 60' long and he said that length was no problem. To keep the dish from being over a living space he suggested an area in the overhang.
Now the installer put the ground directly below the dish and left it for me to hook up. Which is fine, I can buy another ground rod. He told me the distance was too far to run a ground to the other end of the house. The other thing he did and I think this might be the problem.... the dish is clearly mounted over a living space.
