We had a nasty storm with winds of 60-70 mph roll through the area yesterday. Now today when (for the first time since the storm) i go to turn on my receivers i get searching for satellite signal (771). Does this mean the dish was moved by the strong winds or is it something else? How much will DirecTV charge me for someone to come out and fix it (I know nothing about dishes and my dad doesn't get off work til dark)?
