Tried another week, still cannot get any signal. The “signal level” is always under 4%, the same level as no cable connected. We tried all possible ways trying to get any signals but nothing. We switched a little each time within the possible directions and also changed angle a little each time but nowhere to get signal. We even hold dish by hands, and move-stop and move-stop scanning the sky but no signal found. We think there are two possible reasons:

1. We didn’t connect the LNB (there are four outputs, L1 C1 L2 C2) correctly:
Our cable connection is totally like this connection (the same LNB as ours): http://www.sadoun.com/Sat/Products/Invacom/invacom-qph-031-7.JPG, L1 and C2 are used. But on the installation configuration diagrams, http://www.sadoun.com/Sat/Products/Invacom/Invacom-lnb-b.gif
, we cannot found a match one. There are four different configuration, we simply don’t know which one we should follow.

Our switch is this one, http://www.sadoun.com/Sat/Products/S/S-SM21H-2-way-switch.htm . We don’t know how to connect the LNB to this switch. Anybody can help us?

2. The LNB is broken and cannot get signal or transfer signal to the receiver. How can tell if the LNB is working or not?

We will try different connection tomorrow to see if we can find anything.

Thanks,

first take the switch out of the picture hook to the L1 and try to get signal first also leave the motor out for now find a sat with a active transponder make sure the numbers match in your receiver once you find a signal this way then you can install the motor and the switch.
