Armyman,
Welcome back to CONUS. I was in the 101st a long time ago, but still remember the abbreviations. Also had to pull some reserve duty at Ft. Carson--but on to Voom.
Line of sight is to the East, and is much different than Dish. Be sure to check that out first. There have been cases where installers take 1 look and announce that there is no line of sight, and pack up their stuff and di di.
I've had Voom since January, and ordered directly from Voom over the phone. At that time, there was no afilliation with Crutchfield. But I've heard Crutchfield is a great company, and they might be a good way to go, as long as there is no price difference. I say that because Voom customer service can be less than stellar, depending on who you get.
I've also had the 18 inch dish since initial installation, and it has been fine. I lose the signal briefly when some of the heavy thunderstorms roll in, but switch to OTA when that happens. Satellite will go out for 10-15 minutes, but that's OK. Good luck with the decision making process. There are lots of options. If you go with Voom, this forum is great for getting any problems straightened out.
