I got one C-Band LNB and two Ku-Band LNB on one 5 feet solid dish. And i connect those cables to 4 ways diseqc switch like this :

C-Band -> LNB1
KU-Band -> LNB2
KU-Band -> LNB3
Nil -> LNB4
to receiver-> Diseqc receiver

My question is why only ONE KU-Band LNB receive signal and the other one KU-Band LNB is not working??? And my C-Band is working perfectly... What should I do???


Another question again - what is the different between DISEqC 2.0 and 0/22K ToneSwitching???

I'm assuming that the non-working lnb has been tested with a direct cable and is working?

DiseqC switching is far more complex than the pretty straightforward on/off Tone switching.

What, so you are saying that the lnb doesn't work on direct cable connection either?

If you haven't already, try the LNb on the spare DiseqC port, also what are your diseqC settings in the receiver, almost sounds as if the receiver is only seeing a 2 way diseqC switch.

You would appear to have tried all of the standard logical solutions, may be an outside chance that your receiver DiseqC versions are not compatible with the switch, perhaps try and borrow another one.
