6. Aligning the antenna

With regard to the direction (Azimuth) and the inclination

(Elevation), the antenna must be accurately aligned to

the satellite. For multifeed reception it is necessary to

align the antenna to the satelltie with the weaker signal

level.

a) Setting the inclination (Elevation)

 Loosen the screws on the elevation scale – the one on

the left as well as the one on the right of the mast

bracket!

 Attention! Do not loosen the nuts on the upper part of

the mast bracket – these nuts have been tightened

with a fixed torque in the factory.

 Now set the elevation – You find the correct angle of

the elevation in the mounting instructions supplied

with the feed system. If you do not know the angle,

first set the elevation initially to about 30°.

 Hand-tighten just one of the two screws on the

elevation scale.

b) Setting the direction (Azimuth)

For the following steps you need an assistant if you can-

not operate an antenna measuring instrument nor watch

on your television set which you have connected to a sa-

tellite receiver the result of your alignment work.

 Select on your satellite receiver a programme well

known in order to make sure you have aligned to the

desired satellite.

 Slacken the wing nuts on the mast bracket just

slightly.

 … and turn the antenna roughly towards the south.

Then slowly turn the antenna around the mast axle –

to the left and then to the right, until you obtain the

best picture for the chosen programme.

 Next tighten the wing nuts, but only to the extent that

the antenna cannot turn.
