Hi, I have Channel Master 180 and I want to try multifocus. Now I have the dish stable positioned to 28,2 and I want to add other LNB for 36 KU or 21,5 Ku. I tested it today at 26E and results are not good. I will do more tests. Does somebody try to add more LNBs on big offset dish?
 
The 1.8 will have a single focus point for optimal reception. Moving off the prime focal point is not going to provide anywhere near the same gain.

Better to motorise.
 
And if you can't do a motorized system, then a wide beamwidth elliptical dish may work, all you would need is one with about a 20 degree beamwidth, then the proper multi LNB bracket.
