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.
