| Guide to
Installing a KU Horizon to Horizon motor - Strong 4653X screenshots |
Before you start, you should be aware of the
satellites that are available using a KU band dish and motor. When we talk
of KU band dishes, we are referring to dishes generally between 0.65m and 1.2m
in diameter. In most
areas of Australia, you will be able to receive NSS6, Asiasat4, Optus
D2, Optus C1, Optus D1, Intelsat8 and Intelsat2 and in Eastern Australia, INTELSAT701.
Most of these satellites carry either pay TV or
free to air, foreign language programs. For a list of the most common
programs on these satellites, click
here .
First, choose a location on your property that
will allow the dish to 'see' the satellites from West to East keeping in mind
that as the dish rotates, the elevation
angle decreases so make sure there are no trees or buildings in the way.
Install your pole mount using a
spirit level to ensure that the pole is vertically plumb level.
This is important.
Now attach the satellite dish to
the motor and ensure that the dish is aligned to the centre line of the motor
pole. Tighten up the dish U bolts firmly. Lift the entire
assembly onto your mast and tighten the motor U bolts up (not too tight as
you'll need to adjust this)

Set the elevation on the motor bracket to match your latitude. This
conversion has already been calculated by the motor manufacturer so setting the
elevation is easy. You can get your latitude from
this website.
The picture above shows the setting for Brisbane but this setting will vary
depending on your geographic location.
You'll now need to set the declination angle.
This angle is set by adjusting the dish elevation assembly. Using the
chart below, find your declination angle and deduct this from 40. The
answer will equal your declination angle. See the picture below.

Switch off your decoder and
connect a coaxial cable from the 'DISH IN' or 'LNB IN' on the back of the
decoder and run this up to the
motor marked 'REC'. Now connect a short cable
from 'LNB' on the motor to the LNB on the end of your dish. Make sure the
cables will not foul on the dish as it rotates.

Switch on your decoder. This
will send the power up the coaxial cable to the motor and LNB. Click
here to find your latitude and longitude. Now that you have your lat/long, visit this
link
and enter 156° into the satellite orbit field, enter your latitude (remember to
enter it as a minus figure) and longitude
into the site lat and long fields and click to calculate results. The
picture should look like the one below except your lat and long may be
different:

Note the dish azimuth relative to
true north (X°) field. Pressing the manual East button on the motor,
rotate the dish until the directional degree indicator on the top of the motor
is pointing to X°. Go into the decoder's motorised settings screen
(assuming you've already set up the LNB settings) and enter the information from
the screen below:

Moving the entire assembly, find
signal on Optus C1. You may have to vary your elevation and/or declination
angle slightly to fine tune. Once maximum signal is acquired, tighten the
whole assembly. You should now be able to track most satellites using the
motorized option within the receiver menu storing each position as you go.
Be sure to use frequencies that are broadcast into Australia on each satellite.
