This system, recognized as a standard by all sat receiver's manufacturers, needs many adjustments to obtain correct installation of the dish correct pointing to the South, manual research of all satellites, setting of limits, etc. Since , the main aim of STAB research has been to solve all possible problems connected to installation of the motor and to enable users to buy the STAB motor from their retailer and to install it easily everywhere in the world. It is a calculation system processed by STAB , and given free to all manufacturers of sat receivers or PC cards, which enables the receiver to calculate the position of all satellites in orbit with a precision lower than 1 meter with reference to the place of installation. All this in a completely automatic mode and with no specific technical knowledge required, either during installation or use. This new standard provides that the models HH and HH implements a sound system in order to help in pointing the satellite. With these data and following the instruction manual, everyone can install a STAB rotor system.

Installing the Motor 1. Check the pole - ensure that the mounting pole is perfectly straight with a level or inclinometer. If the pole is not level, your dish will not properly track the arc of satellites. Attach the Diseqc motor to the pole - tighten the motor fittings. Set the elevation angle on the motor - the elevation angle on the motor will be based on the latitude of your location.
The manual for the motor will tell you what to set this angle to or alternatively, you can use the following table:. Set the adjusted declination angle on the dish - your latitude will also determine the declination angle - see above.
Most diseqc motors use a special adjusted declination angle formula based on the tilt of the rotating motor shaft which will again be specified in your manual.
For example, Athlone, with latitude of 53 degrees, will require a declination angle of approximately 7 degrees. A Moteck SG, a common diseqc motor, uses the formula 30 — declination angle. So for Athlone the adjusted declination angle is 23 degrees i. This angle can be set according to the markings on the side of the dish.
Slightly loosen the motor fittings - this will enable you to just rotate the motor about the pole. Don't loosen the fittings too much or it will complicate matters. Rotate the dish and motor until you see activity on the signal meter - rotate slowly both the dish and motor on the pole until the signal meter is at a maximum. A compass or the position of the sun may be useful in locating true south. Rotating the dish and motor. Note: For people located on the east coast of Ireland, Atlantic Bird 3 at 5 West may provide better tracking.
In that case, use the same procedure as above, but with the France 2 transponder , V, as your reference. Enter you latitude and longitude into the receiver - enter your location coordinates into the the USALS menu of your receiver.
Rotate the dish and motor until you see activity on the signal meter - loosen the pole fittings slightly and rotate slowly both the dish and motor on the pole until the signal meter is at a maximum.
If you don't have a signal meter, then watch the quality meter on the satellite receiver which has been tuned to an active transponder. Tighten the fittings - once the satellite has been found and the signal is at a maximum, tighten the motor fittings to the pole to ensure everything is firmly locked in position.
If you run into problems, firstly recheck the pole is level - this is critical for proper tracking. Double check your elevation and declination angles and ensure the motor axis is properly aligned with true south. The following diagram will help you to locate any faults.

Beacon Transponders. Diseqc motors offer a cheap and convenient method for tracking the Clarke Belt with your satellite dish. They can be easily aligned if you take a few initial precautions and follow the steps outlined below. Installing the Motor. For example, Athlone, which has a latitude of 53 degrees, will require an elevation angle of 36 degrees. The angle can be set according to the markings on the side of the motor. Some motors even include the latitude markings as an additional aid. Setting the elevation angle.
Setting the adjusted declination angle. Note: If you have a different model of motor, it will use a different formula for the adjusted declination angle.
This method relies on aligning the motor with true south using a satellite which is positioned at or near true south for your location.
In this case, we will use Atlantic Bird 2 located at 8 West as our reference for true south. This is due to the fact that it is more precise to align your dish at the eastern or western extremes of the arc than at the top of the arc i. A good choice is Turksat at 42E as it has a strong signal over Ireland. Testing your alignment. Once you believe the motor has been properly aligned, it's a good idea to confirm with a few tests. We will use 5 satellites which are spread across the Clarke Belt.
How To Install a USALS Motor - Condensed Version
Please watch the videos below then follow the following steps carefully to get your motorized system installed quickly. Select your installation site carefully!!! There must be a clear line of sight between the required satellites signal source and the entire surface of the dish. The line of sight must be free from obstructions, such as trees, roof tiles etc. It is very important to make sure the HH motor is fixed to a perfectly vertical plumb mast Picture 1. Time spent measuring this accurately will save you hours later on. Pictures 1.
Universal Satellites Automatic Location System
It is used in conjunction with the DiSEqC 1. Software on the satellite receiver or external positioner calculates the position of all available satellites from an initial location input by the user , which is the latitude and longitude relative to Earth. This is adjusted automatically and does not require previous technical knowledge. Compared to DiSEqC 1. Pointing to a known satellite position for example Receivers are aligned to the satellite most southern to their position in the northern hemisphere, or the northernmost in the southern hemisphere.
Installing a Motorized Satellite System with an HH-Mount Motor, DiSEqC & USALS Compatible Motors
Installing the Motor 1. Check the pole - ensure that the mounting pole is perfectly straight with a level or inclinometer. If the pole is not level, your dish will not properly track the arc of satellites. Attach the Diseqc motor to the pole - tighten the motor fittings.
