The Magic Rainbow
Satellite Dish pointing explained
You must have a receiver that can control a H to H motor using DiSeQC 1.2 commands. 1.0 will not work The following receivers have the ability to control the SG2100 drive. BEC 6600+, 1000, 2000, Satworks 3688, and the Coship 2300, 5100, and some pci cards. The following receivers do not have DiSEqC ability, Coship 3188c, and Satworks 3618. Most older receivers such as the Zinwell and the Star Pro do not have DiSeQC 1.2 ability. The Digibox will allow any receiver to be used with a motor.
Think of a thin rainbow starting at the east horizon, streaming high across the sky and disappearing at the western horizon. This is where the geosynchronis satellites are, in a thin line across the sky. For most users east of the Rockies will look at the western part of the rainbow, those in the western part of the country look mainly at the rainbow to the east. The reason for this is because of the angles of the satellites from your location. From here in Northern Kentucky, as like everywhere, the highest part of our satellite rainbow is due South. We are at a longitude of 85 degrees west which places satellite AMC-2 due south at an elevation of about 45 degrees. The satellite rainbow streams to the west disappearing behind a neighbors house. In other words the rainbow stretches from 45 degrees up at due south disappearing into the ground in the west.
Now populate the rainbow with satellites, some 300 spread all around the world. Most of the satellites that we deal with are a down the western side of the rainbow. The are like dots within the rainbow. We must land on the right dot when aiming our dish.
When installing our dish we want to mount the part of the mount that the dish or H to H drive sits on as close to plumb, straight up and down, as we can so the dish will sweep horizontally as we turn the dish on the mount. We assemble assemble our antenna or dish and set the elevation according to the information provided by Taylor Enterprises. For us in Ky., Telstar 5 would be at 43.1 degrees elevation. We assemble our dish, set the elevation according to the scale on the side of the dish and if we are lucky we can swing right over to the bird. This sometimes works for a small Dish Network dish but often not for a 0.76 meter dish.
Think of it this way, the satellite is a dot within the rainbow and when you turn your dish you are sweeping horizontally across the rainbow. Think of a paint brush sweeping horizontally across the rainbow and you want to paint your satellite.
On the BEC you find a station that you know is active on the satellite you want, enter "menu" (7 o'clock button) scroll down to "installation" and over and down to "transponder setup". Press enter "central button" and a menu will open up. Look at the two power bars at the bottom of the screen. The power bars will show a signal when the rainbow is crossed, and they will turn yellow when your satellite is found. The receiver looks for the specific frequency and symbol rate and turns yellow when it is found. On the Coship 2300 you will have to note the frequency that the particular channel at the bottom of the screen before pressing "menu" and adjust the TP line so the frequency matches your station. The BEC does that automatically. Now lets go find a YELLOW POWER BAR at the bottom of the screen!
The darn thing doesn't work,,, why???
You are trying to paint a satellite 22,000 miles out in the sky with a $100 dish. The elevation scale on the side of the dish is only approximate. Your mount is not absolutely plumb and you are trying to hit a bird 22k miles out in a rainbow. The bigger the dish the narrower your paint brush, that is why a 20 inch Dish Network dish is easier to aim then a 32 inch dish. The solution is to run your brush a little higher or a little lower. You do this by adjusting the elevation up or down a degree or two or three or so. Move the dish slowly and watch for the yellow bar. One more thing, you can NOT shoot through trees with leaves and you can NOT have a non power passing splitter in the coax going to your receiver like cable companies often leave in the walls. Real old coax may not work at all.
By now you should have your system up and running!
BEC Screen Shots;
Note Yellow bars, the dish is locked on Galaxy 10
Satwork ST3688 with SG 2100 H to H motor; Set up the mount and motor as instructed in directions that came with the motor. Be sure the mount that the motor is mounted to is plumb. Aim dish south using a compass by swinging the mount on the pole. From the remote press "menu", and scroll to "system setting" then "antenna configuration", "ok". This opens a new screen. At this point you will want to make sure that you are on a fairly low satellite like Telstar 5 ku and the transponder is set to a know active satellite such as 12152 or 12177. Unfortunately this menu does not give sr or polarity info. Scroll down to DiSEqC and press the right arrow to "motor" and press the green button on your remote which will open a new screen to the right. From "set limit" choose east and from line one move the positioner to a point to to the east that is just past the maximum point that you think you will need to swing the dish, then store the position. Do the same for the west. With the receiver set to a know active bouquet, move the dish toward the position of the satellite which will be to the west in all places east of about Oklahoma City or the east from the west coast. Now comes the tricky part. You will have to swing the mount back and forth on the pole slightly. This helps to put the dish on the arc. If you have a meter, this will help to identify the location of the arc containing the satellites. When your dish hits Telstar 5, you will see the quality bar turn red and move to about 40%. You have now found t5 and the magic arc. Now try a lower satellite such as G10. You may need to slightly move the motor to repeak the dish. Now go through and place the rest of the birds in memory. See page 4. in your direction manual. Your manual may give slightly different directions but this menu usually works for us.
