Installing a motorised satellite
system ...
EQUIPMENT NEEDED
A dish usually of a minimum of
80 cm, a motormount, and a receiver
As most countries are converting
to Digital from Analogue you will need one of the current crop
of Digital receivers, although some manufacturers make Digital /
Analogue units if is a mixture of channels you require.
The principal of a motorised
system is that the dish moves from east to west to track the
satellites positioned along the Clarke belt. In this method the
whole of the dish is facing the satellite it is positioned at ie
19 degrees, 13 degrees ets, etc.
There are 2 types of motormount
currently used - A 36 volt motor type which is powered by the
Receiver, consisting of 4 wires - 2 to provide 36 volts to move
the mount east to west, and 2 for the reed sensor on the mount
which helps the receiver calculate it's position. These are
generally H-H mounts or actuator arms.
The other type is a DISEQC
motormount. This utilises a datastream passed up the LNB lead to
the mount, this means that only one co-axial cable is needed for
installation.
INSTALLATION
Installation involves the
setting up of your mount to track the satellites along the
Clarke
belt east to west, this is generally done with the aid of an
inclinometer and a signal strength meter or spectrum analyser.
Incorrect alignment usually results in the mount only tracking
part of the arc and only a few of the available satellites being
received.
WHAT CAN I RECEIVE
When correctly installed your
satellite system will be able to receive a multitude of TV and
Radio channels from around the world.
