New here and need some help.. First off I am a installer for dish network.. So I understand dish. But I now nothing about directv. My dad has directv. Every time it gets stormy or windy he looses only his HD channels..This has happened sice his install a year ago. He has really high signal strenghts on 101 and 110 and 119 . But 103 ca and 99c are really low. Now with dish I need to put my super buddy on 119 and the number one port and peak it out. What do I do for directv. I really think that the skew might just be off.. I haven't looked at it yet.. I will be tomorrow..any help is much appreciated.
