How to Align a Slimline

    Verify the Existing Mount

    • 1). Verify that the satellite dish mast has 6 hex head bolts into the foot plate. Verify that the mast is supported by 2 extension monopoles, each anchored to the roof deck with 2 hex head bolts. Tighten any loose bolts on the mast, foot plates, and dish collar assembly that clamps around the mast.

    • 2). Attach the satellite meter to one of the leads directly connected to the Slimline KAKU LNB via 24"RG6 coax jumper. Preset the elevation and skew settings on the dish according to the rough alignment measurements based on the dish's geographic location. Turn on the Satellite meter, and select the "101 DirecTV kaku" satellite. Sweep the dish slowly from due south toward the west, looking for signal acquisition on the satellite meter. Once the signal is acquired, slowly sweep the dish through a 10 degree arc to the point at which the signal is strongest. Tighten down the 3 1/2-inch carriage bolts and nuts on the collar around the dish mast. The Sliimline dish is now "rough aligned."

    • 3). Loosen the 2 1/2-inch nuts on either side of the back collar assembly that hold the dish in place vertically. Loosen the 2 1/2-inch nuts on the underside of the back collar assembly that hold the dish in place horizontally.

    • 4). Return to the satellite meter. Use the 1/2-inch wrench to turn the vertical elevation adjustment screw two complete turns counter-clockwise. Take note of the signal strength on the meter. It should be in the range of 40 percent to 60 percent strength. This is the "beginning signal strength." Turn the same adjustment screw at least 4 full rotations clockwise, and then continue until the signal strength showing on the meter is identical to the beginning signal strength.

      Take note of the total number of rotations of the adjustment screws needed to attain matching signal strengths at the beginning and end of the alignment process. Turn the same adjustment screw back in the counter-clockwise direction exactly 1/2 of the total rotations used to find matching signal strengths.

      For example: If the beginning signal strength was 55 percent, and the screw was turned 6 full rotations to attain the same 55 percent, turn the adjustment screw 3 full rotations back in the counterclockwise direction. This will set the dish in the center of the signal strength in the vertical direction. Tighten the 1/2inch nuts to secure the vertical adjustment on the dish.

    • 5). Use the 1/2-inch wrench to turn the horizontal or "asimuth" elevation adjustment screw two complete turns counter-clockwise. Take note of the signal strength on the meter. Again, it should be in the range of 40 percent to 60 percent strength. This is the "beginning signal strength." Turn the same adjustment screw at least four full turns clockwise, and then continue until the signal strength showing on the meter is identical to the beginning signal strength. Take note of the total number of rotations of the adjustment screws needed to attain matching signal strengths at the beginning and end of the aligning process. Turn the same adjustment screw back in the counter clockwise direction exactly 1/2 of the total rotations used to find matching signal strengths. Tighten the 2 1/2-inch nuts under the front edge of the dish back collar assembly to secure the azimuth adjustment process. The dish is now aligned.
