I'm supposed to be having my AT9 dish replaced with the newer Slimline AU9 this Friday and I was hoping some of you might have some tips as to what to look for to make sure the alignment is done properly. I ask this because when my AT9 was installed a little over a year ago, the installers never did the dithering to fine tune the signal. They peaked one satellite (I forget which) and told me that a high signal here would be sufficient for everything else. And, to be fair, I have been getting a good picture with solid signals strengths on almost all my transponders (mid to high nineties except for ones with 0s or very low signals in the 20s to 40s). But this doesn't jibe with what I've read elsewhere about how to align a 5 lnb dish. The only signals I get which look a bit low to me are on sat 103 where I get a 79, 85, and 79 on the three transponders that aren't N/A or 0. Should I ask the installers to get my numbers higher on 103 or are these good enough? Or is there anything in particular you think I should look for to make sure they do the job right?
