Tune Up Your Dish (Ku-Band)


Q.

I had a storm and now I don't have a picture. How do I fine tune my dish outside?

A.

Many storms produce heavy winds that can turn your dish on the pole, causing a loss of picture. To correct the problem, try these Five Easy Steps To Dish Alignment. NOTE: DO NOT align your dish if the wind is greater than 5 mph.
  Step 1:

Install pole or mount, making sure the pole is level and plumb. If the pole is not level and plumb, tracking of the dish will be difficult to obtain. A post level make the job easier.

  Step 2:

Attach the dish to the motor (A): Make sure it is at the center of the mounting tube. According to the latitude of your location, set the motor elevation angle via the Elevation/Latitude scale in the SG2100 manual on both sides of the motor.

Set the angle of the dish (B): According to the latitude of your location, find the Declination Angle by the Angle Table in the SG-2100 manual. Set the Declination Angle by the scale on the dish. The reading on the Dish scale should be 30° minus declination angle.

  Step 3:

Loosen the mount-to-pole bolts slightly. Rotate the dish east and west just enough to get the best signal. If possible use a meter. Tighten bolts. Adjust the elevation bolt up or down to fine tune the picture. Lock down the elevation. Do not use the elevation bolt for any other adjustments.

 

  Step 4:

With your dish mover, move the dish to the farthest satellite east or west. Find a strong signal.

 

  Step 5:

Put a piece of masking tape on the ground pole and another piece directly above it on the polar mount canister. Make a straight line across the two. This is a starting point for the tuning phase. Once you have a picture on your TV, from the front of the dish, gently lift up on the face of the dish about an inch or so. Does this make the picture better? See corrective action below.

Corrective Action on a Western Satellite

  • If the picture got better, loosen the mount-to-pole bolts. Rotate the entire mount and dish on the ground pole to the west about an inch on your reference line. Tighten bolts and move the dish with your dish mover until the best picture appears. Repeat until picture degrades by lifting up and pushing down on the face of the dish.
  • If the picture got worse, loosen the mount-to-pole bolts. Rotate the entire mount and dish on the ground pole to the east about 1/8" on your reference line. Tighten bolts and with your dish mover, move the dish until the best picture appears. You may have to adjust your polarity. Repeat until picture degrades by lifting and pushing down on the face of the dish.
  • If you are using an eastern satellite, just reverse the direction you rotate the system on the ground pole.
  • A Skyvision Tune-Up Kit is an excellent investment for all dish owners. It will help you peak your dish whenever you feel you are not getting the best from your system.

 

MORE HELPFUL TUNE-UP TIPS

  From time to time cable ends can get corroded or go bad. It is recommended that you replace the cable end connectors out at your LNB. Here is the perfect kit to help you with that.

Also check for splices in your cable run. If you find one, you may need a Ribbon Cable Splice Kit to get your cable spliced properly.

Skyvision also carries an array of tools to help tune a dish. Check out all the tools that will help you do it yourself.

There are times when you could lose your picture with no warning or during good weather. A good percentage of the time the cause is a faulty or failing LNB. We would suggest at that point to change your LNB. See the LNBs we offer. Get information on troubleshooting your LNB.

Site Data Coordinates are helpful when the 5 Easy Steps To Alignment alone are not enough to get your dish back in alignment. They are a great tool for any do-it-yourselfer. Skyvision offers the Site Data Coordinates and 5 Easy Steps To Alignment.
