I am in eastern pa and just recently had DN installed. In having the roof redone I had to bring the dish down and install it on a pole that had a dish on it prior to mounting it on the roof. I changed no settings on the dish and clamped it level and plumb. I have everything except HD channels USA, TNT. My question is in looking at the settings the tech set the dish to the skew was set at 90 degrees but using dishpointer they say the skew should be - 16.2 for my address. So does skew matter in this situation?
