C Band

[2Bobs]

This is my first C band dish I have worked on Done DSS since it came out. I have a used one i'm setting up fpr G11, I have not been able to get a signal, do the 3 #18 wires on side of LNB have to be hooked uo and to where if (yes).
Thank you

to SatelliteGuys...Red, White and Black right? these control the Polarity H and V on your LNB (half of the transponders are one, half the other)

If you are trying to start from scratch with components that require some learning curve give this link a shot.

I'll tell you, this satellite business in quite interesting to say the least!

It is the "communications" business, yet it is typical for very little "communicating" to go on.

This is between manufacturers and customers and between manufacturers of different equipment.

Besides the manufacturers providing few or no instructions with the equipment you buy...

your typical C-band dish requires a two wire 36 volt connection to move the dish, a two wire sensor connection to the positioner, a coax connection to the LNB, and a 3 wire connection to the "polorizer" (H/V) on the LNB "feed horn".

OK fine!

Most receivers say they can receive C or Ku, YET there is NO connection on the receiver for 36 V, OR the two wire sensor, OR the 3 wire polorizer!

So how exactly are you supposed to get C band with these receivers?

Note: They will work fine with a smaller Ku dish with a diseqc positioner and coax cable 13/18 volt controlled polorizer (H/V).

So it is possible to buy a C setup which will not work. A couple of manufacturers have "come to the rescue" though!

There is a coax "diseqc to 36 volt" positioner add on unit to solve part of this problem...

And there is a C/Ku LNBF which easily mounts to a prime focus dish which controls the H/V via the coax (need to get correct model for your receiver BSC621 or BSC621-2)...

First you hook the DVB receiver up to your analog (4dtv) receiver like this:

Then you program the DVB receiver to pick up C-band programming.

And there is a C/Ku LNBF which easily mounts to a prime focus dish which controls the H/V via the coax (need to get correct model for your receiver BSC621 or BSC621-2)...

The 4dtv will not work with the BSC621-2, because it is a Universal LNBF and the 4dtv needs a Standard LNBF to work. The BSC621 will work...
