Step by Step Manual

1 Prepare the satellite dish



Determine the angle for the satellites

It is necessary to know the approximate position on the

horizon in order to quickly align to the correct satellites.

You can either use the simple online calculator

which you can find at

www.durline.de/tools/satcalc.html

or you can scan the adjacent QR code.

Or:

Reference directions for the most common private and public broadcasters,

such as Sky, can be found in the following table.

Video tutorial:

Rule of thumb:

Satellites that can be received in Europe are found on

the southern horizon. The southern point corresponds to 180°.

Turn in a easterly direction (to the left) or a westerly direction

(to the right) from this point. Astra 19.2°E is located a few degrees to the east,

so you therefore need to turn to the left.

It is also necessary to ensure that the antenna is adjusted to align with the

correct elevation angle.

You can use the satellite dishes on your neighbours' rooves to help you to

judge the correct angle.



Roughly align your satellite dish

You now need to align the antenna towards the direction in the sky where you expect

to find the satellite.

Elevation angle: Use the antenna dial (back part).

Azimuth angle: align using a compass as your guide (e.g. smartphone/satellite finder).

2 Start operating the Satfinder

LNB



2.1 Connect the satellite finder with the LNB

Use the coaxial cable that was included with the product – connect the

"LNB" connector to the LNB output.



2.2 Connect the receiver/power supply (receiver is off)

Connect the (receiver) supply cable to the connector that is labelled "receiver".



2.3 Switch on the receiver/power supply

The receiver now takes over the satellite finder's power supply –

the satellite finder is activated and the display is illuminated.

Depending on the LNB type or if the antenna is tilted too far in a

downwards direction, it can be the case that due to reflections, the

satellite finder will display a reading even though a satellite is not being

received. It is therefore initially important to always approximately set

the angle on the antenna (elevation, azimuth) and to ensure that there

is a clear view of the sky.

Adjusting the satellite dish more precisely



3.1 CAREFULLY turn the satellite dish left and right –

take into account the level display and buzzer volume

Turn SLOWLY.

When the antenna is roughly aligned, the level display moves to the

right and the buzzer goes off.

3.2 Turn the controller so that the needle lies

approximately in the middle of the level display

It is then easy to see whether your adjustments are improving or

worsening the level.

If the needle moves completely to the right (or left), it is

necessary to readjust the level with the level adjuster.



3.3 Carefully turn and tilt the antenna until you have moved it

into the optimum position

The antenna is in the optimum position when the signal level can not

be increased anymore.

It is often possible to slightly increase the quality if you

turn the LNB in its retaining clamp in small increments.

(It is not necessary to optimise the skew for Astra 19.2°!)

Checking the TV picture/removing the Satfinder



4.1 Check the picture of a number of channels on your TV

(if necessary, start a channel search)

It is most likely that the satellite dish is aligned towards a different

satellite if you are unable to tune into a channel or if you are tuned into

an incorrect channel. Some satellites are located in close proximity to

each other. --> Check the Azimuth angle and adjust again.



4.2 Switch off the receiver/power supply

Firstly, separate the receiver from the mains to avoid short circuiting.



4.3 Fasten the satellite dish crosswise and

remove the satellite finder from the signal path

Finally, connect the supply cable to LNB - job completed!
