I got HR20 over a month ago, I have had 4 visits from DirectTV to mount the dish, within a day or 2 I would lose signal since the dish would move. I finally got feed up and told DirecTV i was done with there installers, and im hiring a professional installer to do the work. They agreed to reimburse me for the install, we will see if they really do it when I send them the bill for 215 dollars.
