My first experience installing my Direcway dish with DirectTV as well. It took me six hours of trial & many errors to finally get it right.
I must say that four of the six hours were spent getting the tri-pod right, reading & re-reading the manual, plugging the signal meter in backwards, and getting the "feel" of dish adjusting.
Next time should only take half the time and I can foresee only about an hour as I get better.
We've been without internet & TV for the last three days and it felt like living in a black hole.
My one suggestion to any first-timer. Get someone to help you who has done this before. If not possible, be patient. you can do it.
