From what I am told they are fairly tedious to set up as a carry out, especially if you move frequently, as we do. You have to align up to 5 satellites depending on your service level.
For this reason, we bit the bullet and shelled out for the full auto Directv Winegard slimline. They have come way down in price.( I didn't get it from CW).
After 6 months it has been flawless and has saved a lot of frustration. Very happy with it at this point.
I used a carry out for years. If you stay put for extended periods the carry-out probably makes more sense money wise.
After driving 400-500 miles I prefer not to fiddle with a dish. Go in push a button. No zip codes, azmuth,elevation,tilt. In 5 minutes you have full HD.
Unbelievably, this thing even got a decent signal through trees at one point. I told the DW it wouldn't work, she did it anyway and it worked.
Good luck, Trace
