The signal is very weak. We've had the dish moved and still not any better. Wind blows TV goes out. Never had that with directv.
If wind is truly enough to take out the signal, then your problems are one or more of the following:
1. tree issues - and wind makes that most likely. Which means to me that your installation isn't correct.
2. Misaimed dish, but the move should have cured that.
3. Poor cable quality
