How to Reposition & Re-Aim a TV DishSatellite dishes must be properly aligned to receive a satisfactory signal. Satellite television dishes need an exact fix on the transmitting satellite to receive a strong signal and even the slightest movement can result in the complete loss of your television picture. Re-aligning a satellite dish needs precision but it is a straightforward task with a little research and basic equipment. Before re-aligning your satellite dish you will need to know your exact geographical location; the position in the sky of the correct satellite; and the angle of reception (azimuth angle). You can get this information and an alignment calculator from satellite "dish pointer" websites. For best results, buy an inexpensive satellite signal meter.
How to re-align your satellite dish1 Switch off your satellite television receiver and all connected equipment and disconnect from the AC power supply. 2 Access your satellite dish with a ladder or steps. 3 Check the dish and dish mount for any sheared or broken bolts and screws and, if necessary, replace them. 4 Identify the Low Noise Block (LNB) at the end of the arm protruding from the dish. 5 Unscrew and detach the output coaxial cable from the LNB. 6 Attach the satellite signal meter, following the manufacturer's instructions. 7 Loosen the bolts or screws attaching the dish to its mount by a half-turn (or by enough to allow some movement vertically and horizontally). 8 Rest your compass on the dish arm and, using the compass, align the dish horizontally to the correct East-West co-ordinates. 9 Tighten bolts or screws on the horizontal axis but leave some "play" to allow a little movement. 10 Slowly move the dish vertically to the correct angle of reception, or azimuth (using the markings on the back of the dish mount as a guide). As you move the dish, your signal meter should emit a high-pitched tone when your dish aligns with the satellite. 11 Tighten bolts or screws on the vertical axis but leave some "play" to allow a little movement. 12 Move the dish very slowly vertically and horizontally until you achieve the maximum signal possible on the satellite signal meter. 13 Tighten all dish/mount bolts and screws firmly and detach the signal meter from the LNB. 14 Re-attach the output coaxial cable to the LNB and weather-proof the joint with tightly wound self-amalgamating tape.
Tips & WarningsIf attempting the re-alignment without a signal meter, follow the same process but leave the coaxial cable attached to the LNB. Use your satellite receiver to "fine tune" to the strongest signal.
