A satellite dish must be lined up to exactly match the position of the overhead satellite. Setting the skew (polarity) of the dish factors in the kind of satellite being accessed; satellites all lie in a curve in the sky but are at different heights from one another. To set the skew on the dish, match the horizontal and vertical positions of the satellite by using a satellite signal finder. A number of these devices are available for sale at electronic or satellite supply stores. No special expertise is needed to use the satellite signal finder for setting the skew.

Instructions

  1. 1

    Unscrew the coaxial cable connected to the coax output on the base of the satellite low noise block amplifier module that receives the satellite transmissions. Screw the coaxial cable into the coax output of the satellite signal finder.

  2. 2

    Screw an end of a coaxial cable into the coax input on the satellite signal finder. Screw the other end into the coax output on the base of the LNB module.

  3. 3

    Twist the "On" knob clockwise until you head a click, or press the power button to turn the satellite signal finder on. Adjust the "Gain" knob if there is one until the needle in the screen begins to quiver--otherwise continue twisting the "On" knob until the needle quivers.

  4. 4

    Loosen the "elevation" knob on the side of the bracket holding the satellite dish in position. Slowly raise the satellite dish until the needle on the satellite signal finder quivers at the highest number available on the scale inside of the screen. Lock down the "elevation" knob to prevent the dish from any further vertical movements.

  5. 5

    Loosen the "azimuth" knob on the side of the bracket. Slowly move the dish from side to side until the needle on the satellite signal finder quivers at the highest number possible. Lock down the "azimuth" knob to prevent the dish from any further horizontal movements.

  6. 6

    Twist the "On" knob counter clockwise until a click is heard to signify that the device is now off--otherwise press the power button to turn it off. Unscrew the coaxial cables from the coax input and output. Unscrew the coaxial cable from the coax output on the LNB module. Connect the coaxial cable that was connected to the coaxial output on the satellite signal finder back on the LNB module.
