Aligning a two-LNB satellite dish is a guess-and-check process that requires the use of the satellite receiver and continued incremental elevation (up/down) and azmimuth (left/right) adjustments to the satellite dish. Despite the fine tuning process necessary during alignment, you don't need a professional technician. With only a wrench and the aid of the satellite receiver, you can align your two-LNB satellite dish without any technical expertise.

Make sure the coaxial cable from your two-LNB satellite dish is plugged securely into your satellite receiver. The coaxial cable runs from the back of the dish's mast inside to your receiver, which should be located near your television. Plug the coaxial cable into the back of the receiver via the port labelled "ANT IN."
Connect the satellite receiver to your television using the standard A/V cable included with your dish and receiver. This cable has three prongs-one red, one white and one yellow-at each end, for a total of six. There are colour-matching red, white and yellow ports on the back of your TV and the back of your receiver. Colour-match the prongs to the ports and plug them in.
Power up the receiver and the TV. Once the receiver boots up a menu will appear. Select the "Signal Meter Screen" option. Have a friend stay with the signal meter screen as you go outside to the two-LNB satellite dish.
Use a wrench to loosen the first of two sets of nuts on the dish. The first are the nuts beside the elevation bolts, located on the back of the dish's mast (your dish also comes with a manual that has a visual guide to the nuts and bolts). With the nuts loosened, make one slight adjustment to the elevation (up/down movement) of the dish every five to seven seconds. After each adjustment, wait several seconds for a report from your friend at the signal meter screen. The signal meter screen provides readings that tell you how close you are to hitting the necessary coordinates for optimal satellite signal reception.
Use your wrench again to loosen the dual LNB arm nuts on the back of the dish's mast. Then, make slight azimuth (left/right) adjustments to the dish as you did with the elevation, and wait for signal meter screen updates. Once the meter screen indicates the coordinates are on target, your dish is successfully aligned.
