You have to move the dish slightly. Either to the left or right, or up or down. This is best left to a tech, but if you have the gumption, then you can do it yourself. You'll need a 7/16" wrench. Put the receiver on the point dish screen (MENU 6,1,1) and go to 129 Transponder 31. You should see a signal there and that's what you are trying to get higher. The easiest way is to have a helper watch that screen as you adjust the dish. You can do this with a cellphone and house phone. Another means is to use a baby monitor and monitor the receiver's pitch just as you would monitor a baby.
When you actually move the dish, loosen the two bolts holding it to the pipe and move the dish just slightly, about 1/4" at a time either left or right. Wait a couple seconds and see how the signal changes. If it gets better, keep going another 1/4" until you see it start to drop. Then you can hone in on it. If it starts to drop right away, you might need to go back the other direction.
Once you have the left/right adjusted (we call this azimuth), you need to lock down those bolts. Lock them down to just about where you feel the wrench might slip. To adjust the up/down (elevation), loosen the two bolts that are on the hash marks near the pipe. Move the dish ever so slightly. When this setting is off, you usually need to go up for more signal since everything may have sagged down a bit from the original install if all the bolts weren't tight.
