1 Prepare the satellite dish

Region

North-west (Dortmund)

North-east (Berlin)

South-west (Stuttgart)

South-east (Munich)

Satellite: Astra 1KR/L/M/N (19.2° O)



3.2 Press the "Attenuation +" or "Attenuation -" button, and carefully turn the adjustment

wheel (right) to keep the signal level bar in the middle (approx. 50%).

->Thus, there remains enough "leeway in the display" when adjusting to identify whether the

reception is getting better or worse.

if the display reaches approx. 99%, attenuate slightly again (button/wheel) and adjust more

precisely.

4 Check the TV picture and remove 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 no programmes or the

wrong programmes are received. Some satellites are 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 the LNB - job completed!

1.1 Determine the angle for the

satellites

It is necessary to know the approximate

position on the horizon in order to be able

to quickly align the

antenna on the correct

satellites. For this

purpose, use the easy

online calculator at

www.durline.de/tools/

satcalc.html

or scan the following QR code.

Or,

You can find reference values for most

private and public channels as well as Sky

in the table below.



1.2 Roughly align your satellite dish

-2°

Now align the antenna in the position in

-2°

the sky where you expect to find the

satellite.

-2°

Azimuth angle: align by compass

(e.g. smartphone compass)

-0°

Elevation angle: Use the antenna

dial (back part).



2.1 Connect the Satfinder 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 supplies the power

to the satellite finder – the satellite finder

starts.

The satellite finder potentially displays a reading,

often 99% or 0%  Turn the adjustment wheel.



2.4 Attenuate the LNB background noise

Depending on the LNB type and background

interference radiation, the satellite finder may

already display a reading even though a satellite

is not being located.

Before beginning the alignment, you must

attenuate the interference radiation/back-

ground noise.

To do this, turn the lateral adjustment wheel or

press "Attenuation" buttons (ATT-), until you

find the threshold value and then adjust the

level to approx. 10%.

Now the satellite finder is ready to display

the satellite signals correctly.



Antenna roughly aligned as described

in step 1?



Satellite finder adjusted as described

in step 2.4?



3.1 Turn the satellite dish CAReFULLY

right and left –

observe signal strength bar or buzzer

volume

If the antenna is roughly aligned,

the signal strength bar in the display

goes up.

The aim is to find the point with the max.

signal level, but not to reach a certain

numerical value (such as 99%).

Keep the signal level display region

at approx 50% by reducing or increasing the

attenuation.

An increase or decrease in the level can thus

be identified.

If attenuation is activated,

"ATT" appears on the display.

The adjustment wheel is very sensitive.

 In addition, use the "Attenuation +/-"

buttons.



3.3 Optimally align the antenna by

gentle turning and tilting

The antenna is optimally aligned

when the signal strength cannot

be increased anymore.

It is often possible to somewhat increase the

quality by turning the LNB in its retaining

clamp in small increments, known as skew

optimisation (not necessary for Astra 19.2°).
