How to install an HH-Mount Motor
DiSEqC & USALS Compatible Motor
Select your installation site carefully!!!
There must be a clear line of sight between the required satellites 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 mast (Picture 1). Time spent measuring this accurately will save you hours later on.

If the HH motor shaft is not at zero degrees (0 reference), you should get it back to zero degrees by connecting the receiver to the mount. The receiver must be on for the HH Motor to move. It’s easier to do this before placing the H-H Motor onto the mast. Once you have done this, the HH Motor should then be disconnected from the receiver. HH Motors are usually set to zero degrees by default from the factory.
Fit the H-H Motor onto the mast and do the nuts up finger tight.
Use an angle finder or the elevation scale sides of the HH Motor to set the elevation angle for the motor (Picture 2). This angle should be equal to the latitude of the installation location.

Fit the dish on the H-H Motor shaft and tighten the nuts. The middle of the dish clamp must be lined up with the centre line on the H-H Motor arm (Picture 3). The LNBF arm, dish clamp, HH Motor, and mast must all be on the same straight line facing TRUE SOUTH (Picture 4).

You will also have to adjust the elevation of the dish to peak the signal.

Elevation angle of the dish is calculated based on the model of the HH motor you are using, as follows:
Satcontrol SM3D12: Equals (46.5 minus declination angle)
STAB Motors (HH100 & HH120): Equals = P - (60 - Location Latitude)
STAB Motors (HH90): Equals = P - (45 - Location Latitude)
Moteck SG2100: Equals (30 minus declination angle)
Declination angle chart is provided below
Aiming at TRUE SOUTH: Move the dish/motor assembly together as one unit East and West by moving the H-H Motor clamp attached to the vertical supporting pole. Make sure the dish remains on the centre line displayed on the H-H Motor arm. You can find TRUE SOUTH by using a compass and by adding or subtracting the magnetic deviation for your area. See the map below to determine how many degrees you need to subtract or add. For example for New York City, the true south will be 180 plus 14 = 194 degrees on the compass.

Tighten the nuts on the HH Motor clamp attached to the supporting pole.
By following the above instructions accurately, you should now have installed your dish on the arc.
Testing your installation:
Re-connect the receiver to the H-H Motor.
Connect the LNB to a signal meter, or use the receiver signal meter on your TV screen.
With the satellite meter still connected, move the dish east by pressing the small east button underneath the H-H Motor (SM3D12) or by using the receiver's remote control (for STAB). For USALS capable receivers, use the USALS feature.
Peak the signal on the meter for the farthest Eastern satellite in the horizon until you believe it is as good as you can get by moving both east and west.
With the satellite meter still connected select a Western satellite and move the dish west.
Peak the signal on the meter until you believe it is as good as you can get by moving both east and west.
With FORTEC STAR receivers, you can use the USALS feature to easily locate the satellites.
Now, tighten the H-H mount on the supporting pole. You are done.

FAQ:
Do I need a separate power line to connect to the HH Motor?
No. The motor gets its power from the receiver using the same coaxial cable running from the receiver to the LNBF on the dish. You simply disconnect the cable from the LNBF. Connect it to the HH Motor. Then run a short coaxial cable between the motor and the LNBF. You are set.
How do I control the motor to move it East / West?
The motor is controlled by the receiver's remote control. All receivers compliant with the DiSEqC 1.2, 1.3, or USALS protocol have the capability to run an HH motor. Once you initially setup the motor on the satellite arc and store the locations of the satellites, you will be able to move between satellites by simply changing the channel.
Does the motor also adjust for variation in elevation on the dish for each satellite?
Yes it does.
Do I need to skew the LNBF on a motorized dish?
No you don't. Just set the skew at 0 and the motor will tilt the whole dish when it moves.
What is the benefit from motorizing my dish?
Well, by adding a motor to your system you will be able to receive satellite channels from several satellites instead from one only. That way you will gain many more channels economically without investing in many dishes and switches.
Where can I find out what channels are available free to air?
There are many free to air channels available in North America on satellites such as Galaxy 10R, AMC4, Telstar 5, AMC3, etc. There are channels from the USA and from around the world. See http://www.lyngsat.com/america.shtml for a complete listing of what is available. Anything with an F designation is FREE TO AIR.
