c. One end of the 10 metre cable supplied is firmly screwed into the “input” of the receiver (or directly into
the TV if it has satellite capability).
d.
The other end of this long cable would normally be screwed into the LNB behind the dish but for now it
should be firmly screwed into the connector marked
receiver
on the satellite finder. (
We supply two
push-on connectors which can be screwed onto the main cable at the satellite dish end and the small
cable that also goes to the LNB. This will minimize any disturbance when removing the sat-finder after
the satellite has been located.)
e. Connect the small piece of cable from the satellite finder to the Multimo’s LNB.
If you are in the U.K. make sure the cable connected to the LNB is coming down at the 5 o’clock
position as you look at the back of the dish. (See below right).
5) Turn on the TV and the satellite receiver. Select the correct “source” for the TV. This is could be AV1,
SCART or HDMI depending how the receiver is connected to the TV.
On the receiver select a UK channel from ASTRA 2, we use SKY NEWS as it is generally one of the
strongest transmissions. The satfinder should now have power going to it.
6) Turn the Multimo towards the north and adjust the “gain control knob”
on the satellite finder until it makes a noise and the needle or LEDs
move to the top of the scale. Now turn the knob down until the sound
just stops. (This can be quite a sensitive operation so take your time).
7) Now, (making sure that there are no obstacles towards the south and
south-east, with the Multimo level and the correct angle of elevation
set), sweep the dish around through east towards the south.
All of a sudden, as the dish points towards the south-east, the satfinder’s sound will increase in volume
and pitch and the needle or LEDs will move towards the top of the scale.
8) Continue turning the dish very gently until the tone and the needle (or lights) reach their maximum point.
9) If you have followed these instructions correctly you should now have a
picture. The signal can be fine tuned by making small adjustments to the
dish both in a horizontal direction and elevation angle. There is often a
useful signal strength screen available on the receiver that will help with
this. Do not adjust the “gain control knob” on the satfinder when doing this.
10) The LNB behind the dish can also be adjusted by turning it to fine tune the
signal strength. This process is called “skewing” the LNB and will be necessary when you are away
from the centre of the footprint. In most areas of G.B., keep the LNB at the position shown at (e) above.
