- DISCUSSION ON TWIN-LNB

Watch out, if Your twin Lnb is for the type used for internal distribution.

If it is, You will only have vertical signal on one and horisontal on the
other.

Perhaps this is a stupid reply, but i´ve experienced it myselfe and it took
me several days to discover that fact.

The twin lnb i´m using now (Cambridge) produces the excact same result
as when i use a single - there should be extremely little difference.

On cirkular polarisation - with the first mentioned twin lnb - i could
notice a
reduction in the signal!

Therefore this reply - perhaps that´s your problem?

Manufacturers of twin output LNBFs include an extra 3dB amplifier stage to
ensure that both outputs are at the same level as a single output LNBF.
As a first step, if you do not have a sat meter available, is to take the
receiver and a portable TV to the antenna, use a short length of coax, 
and check the picture quality there. If the picture is free from sparklies 
then replace your coax or fit an in-line amp. If the picture has some
sparklies
and the set-up is OK, then have your supplier exchange your twin LNBF.

Actually, IRDETO was developed in South Africa for the M-NET pay TV channel
about 15 years ago - http://www.irdeto.co.za/ & http://www.mck.co.za/ - This
was a terrestrial PAY TV channel encoded in a similar format to D2MAC (sound
channels were encoded digitally).   It did not have a smartcard - each decoder
was individually accessed by its serial number over the air.  M-Net did
**VERY** well financially and M-Net subscribers (of whom I was one) probably
helped subsidise the development of all future IRDETO technology.

IRDETO stands for I.R. DE TOONDER, the developer of the M-Net decoder - who I
believe now lives in the Netherlands - and most of the IRDETO development is
now done in the Netherlands (check http://www.irdeto.nl)

Hope this adds to your understanding :-)

Yes start here (1W)
Use the pal signals to align the dish and LNB correctly.
I use a small piece of tin foil over the front of the LNB to make
signals weaker, listening to the audio is often easier than watching the
pictures!
(I assume you have no sat test gear!)
>
>Then what?

Do it again, and again till it is correct!
The weight of the dish and mount on my setup makes the pole bend
slightly! (pole too long!) so i had to compensate by adjusting the
bracket!
>All help and advice appreciated.

The first time ...... Takes a lot of time!
Good luck

I personally got the 1.2 m channelmaster, can get most things even in
heavy rain, and the cost was about the same as a 1m dish.

I have the polar mount that comes with the dish. this is a 3in dia
pole mount thingy, so make sure your bracketry is up to it!

its a good fitted price, I paid 480 including the vat for a pace 508,
1.2m dish 100m control cable, 100m ct100 coax, 10 foot pole and heavy
duty tk brackets. I fitted the whole lot in 4 hours myself, using a
compass and a signal strength meter.

you have to make sure that the pole is absolutely vertical, from there
it is the proverbial bit of piss......
