First things first, check for line of site by making sure you have a clear view of the sky at compass heading and elevation appropriate for your area where you would like to mount the mast. If all is well with that, mount your mast at that location. Before mounting the Dish500, (crucial) make sure with a torpedo level, the mast is perfectly plumb straight up & down, if not, your skew and elevation setting will be incorrect. Next set the skew and elevation for your area on the dish. Once the dish is mounted, snug it so it is not real loose, but not so much that you can’t swing it from left to right. next hook up the meter (you can get a cheapie for $19.00) point the dish far to the left of where your compass heading should be, then slowly swing the dish to the right until the meter reading goes up to it's peaking point, then tighten it up there. Don't swing the dish in from the right or you will accidentally hit Direct TV or the Bell South SAT. If that be the case, the receiver will show good signal, but won't be able to lock on. Also, once you tighten the dish peak the elevation by easily pushing and pulling on the top of the dish to see if you need to adjust the elevation up or down. And you did it. But remember, if you are using a DPP44 switch with a Super Dish, 61*5 needs to go on port 3 and bring the 121 or 105 to port 4. If this is not done, some systems have intermittent signal loss (not all).
Good Luck
