they are easy, just follow the training step-by-step. Everything needs to be done in the right order and you shouldnt have any problems.
i install wildblue, direct, and dish, and I MUCH prefer the wildblue jobs. In my opinion, the dish is much easier to align.
I went through the training almost 2 years ago, and have been installing them since the first satellite lit up in our area, but we had a guy do his first one the other day, and he didnt have any problems at all.
The only thing I have to complain about is the dish comes in a million parts. takes longer to assemble the dish than to mount and align.
So why can't they pre assemble part of the dish. Maybe it is because what they do put together is all loose?!? Or maybe saves them lots of money not having to assemble them at factory?!? That is it money!!! I do like the alignment the dish aligns easily.
