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).

Elevation angle of the dish is
calculated based on the model of the HH motor you are using, as follows:
-
STAB Motors (HH100 &
HH120): Equals = P - (60 -
Location Latitude)
-
STAB Motors (HH90):
Equals = P - (45 - Location
Latitude)
-
Moteck SG2100:
Equals (30 minus declination angle)
-
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.

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.
