Satellite Reception - How
to start ...
Internet by Satellite can be rather interesting,...
on this page I'll help you setup the dish aiming for the Astra satellite
This page is suitable for Satellite TV aswell
as Internet by Satellite!
Mounting a Satellite reception dish for the Astra
(Eutel/Hotbird works similar)
I found this the hardest part of the start of Internet
by Satellite. It's not an easy task to mount and aim the dish. I personally
had to call a friend to get some help (thanks Frank!), so if you can:
call someone who has done this before or call your dealer if you're not
sure you want to do this.
Some brief information about mounting a dish:
- The dish should be aimed at (for the Astra Satellite!):
19.2° East or 28.2° East (compared to South)
- For the Eutel/Hotbird: please adjust it slightly
... I think it's about 5° more to the east.
- Your dish should be mounted outside,
in-house will most likely not work!
- The dish should not be mounted more than 30 meters
from the receiver.
- The dish should (for
most parts of Europe) at least have a 60 cm diameter.
- The dish should have a free sight,
so no houses, trees or whatever in it's sight!
- Check the tilt of the dish (for the Netherlands
between 29 and 30 degrees).
- If you still have to buy an LNB (the "head"),
then you should consider a double or quadriple LNB.
Why a double or quadriple LNB ? Well, usually these
are not that expensive but offer more fun. One can hook up 2 receivers
or a receiver and a DVB-card (for Internet by Satellite) etc... for a
few extra bucks you get a lot more out of that single dish !
As I already told you: see if you an find some help
from a friend or a dealer if you're not sure if you can do this by yourself
... I had a friend helping me too ... so don't feel ashamed.
The instructions below give you an easy way of setting up the dish and
should work for all of you,... the information is based on the information
I found on the Astra Website, experience and luck,...
Step 1: Where to put that dish?
Before we can place a dish, we must know where the Astra
satellite can be found, so we can aim for the right satellite. For the
Netherlands, there is an easy trick (other countries may differ). Coverage
details can be found here.
Take a look at the sky around 12:45 in the beginning
of the afternoon (GMT+1, summertime) and locate the sun. The sun is now
approximately at the same location as the Astra.
For those of you, not living in the Netherlands, or those that just want
to be acurate:
The exact location of the Astra is 19,2° east in relation
to the south. For users of a compass this should be a piece of cake. I
have to admit that I'm not familiar with the use of a compass, I just
used the normal "sun"-trick. It's less acurate but very
simple. If you like to explain to me how to handle a compass then please
mail me !
Also a good trick: take a look at your
neighbours dish (if they have one) - it will give you a pretty good idea
where to aim for.
Some important dish parts:
the LNB a.k.a. "the head" of your dish
vertical tilt settings
You can place the dish anywhere, where the dish has
a free line of sight. No object, like a house or a tree, should be blocking
the sight from the dish to the Astra satellite !
Make sure the dish is mounted stable ! A moving dish
will interfere with reception quality !
Note: The antenna cable should not exceed
a length of 30 meters ! Keep this in mind when looking for a location
for the dish.
Note: mounting the dish on a wall is the
most secure/stable way to mount a dish.
Before you continue: now is the time to mount the satellite
Step 2: Vertical tilt/offset
of the dish ?
In this situation we mean by this the backwards leaning
of the dish. In the chart below you have to locate your position and read
the indication on the right to see the degrees for tilting the dish.
In my situation, living in the south of the Netherlands,
I must position my dish between 29° and 30°, so I'll start by using a
29,5° vertical tilt.
Set the dish tilt, make sure the surface you mounted
the dish on is 100% straight (ie. 90° angle).
The placement of the dish is done using a "brace" with a degree
indication used for the tilt offeset, this picture and the zoomed picture
below will make things a bit easier to understand:
The A marked box in the picture above, is zoomed in
the picture below:
Here we see an 29,5° vertical tilt of the dish ...
Step 3: Hooking up the
We can now hookup the equipment. This can be a regular
satellite receiver of for example a DVB-card for your PC (suitable for
satellite reception). It doens't really matter what you choose to use,
as long as it is capable of displaying the reception signal strength.
We will need this for the fine tuning later on.
In the manual of your equipment you will find how it's
all to be connected.
For all receivers, basically this is how it's done:
The antenna cable goes from the LNB to the SAT-receiver.
A TV-satellite-receiver is hooked up to the TV-set and
a DVB-card is located in your computer.
Keep in mind that for your DVB-card to work properly, you will need to
install drivers and software.
WARNING: Do not yet connect the power
to either of the devices !
Incase you're using a TV-SAT-receiver, you can now connect
the TV and plugin the powercord. Now switch your TV on and set it to the
AV-channel. Usually this is channel zero, E-channel, E1-channel or simply
the A/V-channel (you should be using the SCART or seperate A/V cables
for this to work). On most remote controls the A/V-channel is recognized
by a little arrow with a small box drawn around it.
Now plugin the powercord of the Satellite-receiver and
switch it on.
If you're using a DVB-card, then now is the time to boot your computer.
Now set either the TV-SAT-receiver or the DVB-card software,
to signal-strength indicator. This is different for each receiver, so
you will have to look in the manual for details.
For example, the Technotrend look-a-like DVB-cards indicate
signal strength by starting the DVBData-application, or (if the
application is already running) by double clicking the DVB logo in the
systray (where Windows also runs it's systemclock).
When you're using a Strong SRT8000 satellite-receiver
you can use the remote control and press "menu", "7"
A statusbar will appear, if everything is prefect, the
full bar will be display and will be green. Ofcourse this will very likely
not be the case, that's why we will do some fine-tuning in the next step.
Step 4: Fine-tuning the
We will now start turning the dish with very small steps
in a horizontal direction (ie. left or right - Azimuth). Note that
sitting in front of the dish or toutching the dish will influence the
quality of reception!
Start (for example) by truning it a very little step
to the left. Wait 5 seconds and check the signal indicator of the receiver
or DVB-software. If the signal appears to decrease: turn the dish the
otherway around in small steps again, until the signal is at it's maximum.
This does not need to be the full bar !
Next we will change the vertical tilt (leaning more
or less backwards of the dish). We use the same procedure here as before:
use little steps and start working in one direction until signal lower.
You're done when the signal indicator bar will not become
any better (a full 100% is almost impossible!).
An indicator (here DVB-card software
Note: a 100% signal strength will be very
unlikely to get. Often 70% will do just fine for a good reception.
No lock the bolds by setting them tight. Keep monitoring the signal indicator
since this usually influences the position of the dish.
Tip: tuning the dish is best done with 2 people, or have
the receivers signal indicator within sight (thanks Frank!).
