Setting up your receiver for C/Ku Reception

[RDosetareh]

I received an interesting email from a customer overseas who had ordered a bunch of the DMX741U CKU LNBFs from us and was installing it. Though it's a very important question, it has a very basic answer.

His question was how would he setup receivers to receive both C band reception and Ku band reception when it's the satellite satellite.

The answer is very simple: As far as the receiver is concerned, you have two seperate LNBFs hooked up and will treat the setup as if you are getting signal from 2 seperate satellites. 1 satellite that broadcasts C band and 1 satellite that broadcasts Ku band. So you would create a satellite in your receiver with TP frequencies of the Ku band portion and another satellite in your receiver with TP frequencies of the C band portion. Then you would assign Port A or 1 to the C band and Port B or 2 to Ku band.

I use a c after the sat name for c band to distinguish the 2 sats.

Yeah... Many receivers are also pre-programmed from the factory like that. Some of the older set top boxes however still only have 1 satellite programmed in.

Hello
I installed a KU band lnb on my 36" dish and set it up for AMC 4,got 98% signal,I then removed the lnb and installed the741U ,set the 22khz to on,lnb freq to 10750 and got nothing.I tried rotating the lnb,moved it in and out,no luck,reinstalled kuband lnb,got my sat back.I probably forgot something.The dish is on a rotor and never moved.Any help please?

..........i dont think that lnbf it's gonna work with a 36" dish, that lnbf work with a prime focus (1.80 meter and up).

That lnb is suposed to be a dual kband and c-band.I'm not looking for c band just better ku band.I had a 33" dish with rotor and some transponders were weak so I thought a bigger dish would improve my kband signal.When I reinstalled my linear ku band the signal level went up from 85 to 100 on some stations.I intend to use the 741 U on a future bigger dish.I thought I could use it for KU band for now but it don't work.Live and learn,nice hobby for the terminally retired though.

.....absolutely, bigger dish better signal.
