The LNB you have can pick up both "Linear" and "Circular" signals.
Make sure your RG-6 cable is plugged into one of the "L" ports on the LNB.
Make sure the other end is plugged into the LNB port on Ultra (not ANT port!!!)
In the settings for your system, you must make sure your LNB seting is set to "Standard", and the value is 10750.
If you dont have this set right, it will make it difficult to find the AMC5 signal.
For the
SM3D12 type motor, the setting is calucated from this formula:
46.5 minus Declication angle.
Declination angle is found here:

You are at 40 degrees, so your value from that table is 6.26
So for your location, 46.5 minus 6.26 is 40.24
Use 40 on your dish bracket.
