The SF 2450 B analogue satellite finder with new and improved electronics
enables you to quickly and easily align your satellite system in a precise and
reliable way. Accurate results are provided via both the backlit level display and
an acoustic signal.
This device is very sensitive and can pick up even the weakest signals. Strong
input signals (through powerful satellites or large satellite antennas) can be
easily attenuated using the control dial.
The device can be configured with all types of satellite systems and produces
highly accurate readings.
The satellite finder is powered through the LNB operating voltage by the
receiver/TV or multiswitch and does not require an additional power supply.
• Never open a product that has been connected to an electricity supply
as there is a high risk of electrocuon!
• Never work on satellite equipment during thunderstorms.
• The product must be immediately isolated from the operang voltage if
it comes into contact with uids.
• Do not operate a damaged device.
• The device must be connected and used in accordance with the
user instrucons.
• Non-observance of these instrucons can invalidate your
guarantee.
• This device may only be opened and repaired by qualied personnel
who must observe the applicable instrucons.

Determine the angle for the satellites
It is necessary to know the approximate posion on the
horizon in order to quickly align to the correct satellites.
You can either use the simple online calculator
which you can nd at
www.durline.de/tools/satcalc.html
or you can scan the adjacent QR code.
Or:
 Roughly align your satellite dish
You now need to align the antenna towards the direcon in the sky where you expect
to nd the satellite.
Elevaon angle: Use the antenna dial (back part).
Azimuth angle: align using a compass as your guide (e.g. smartphone/satellite nder).
2 Start operang the Sainder
TV / receiver
LNB
 2.1 Connect the satellite nder 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 o)
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 nder’s power supply –
the satellite nder is acvated and the display is illuminated.
Depending on the LNB type or if the antenna is lted too far in a
downwards direcon, it can be the case that due to reecons, the
satellite nder will display a reading even though a satellite is not being
received. It is therefore inially important to always approximately set
the angle on the antenna (elevaon, azimuth) and to ensure that there
is a clear view of the sky.
3 Adjusng the satellite dish more precisely

3.1 CAREFULLY turn the satellite dish le 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 o.
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 le), it is
necessary to readjust the level with the level adjuster.
 3.3 Carefully turn and lt the antenna unl you have moved it
into the opmum posion
The antenna is in the opmum posion when the signal level can not
be increased anymore.
It is oen possible to slightly increase the quality if you
turn the LNB in its retaining clamp in small increments.
(It is not necessary to opmise the skew for Astra 19.2°!)
4 Checking the TV picture/removing the Sainder
 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!

Reference direcons for the most common private and public broadcasters,
such as Sky, can be found in the following table.

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 direcon (to the le) or a westerly direcon
(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 le.
It is also necessary to ensure that the antenna is adjusted to align with the
correct elevaon angle.
You can use the satellite dishes on your neighbours’ rooves to help you to
judge the correct angle.
