I use an 18" dish for tailgating w/great success. I have a slimline @ home but there is not an issue using your SD home receiver without the slimline. When you're aligning the dish, I find it easiest to first MAKE sure your post is plumb. Pre-set the correct elevation and then just set your receiver to "view meters" and begin to rotate the dish. It's really quite easy. You may find that your receiver will not allow you to get to the right screen when you first power up. Hit exit and then menu and navigate to the setup, "view meters." I have gotten my locals 180 miles south of Cincy. Hope it works for you.decided to go with single lnb for ease of set up and since HD is not an issue. I will post back in a few weeks after we use it.
