Changing from 18" dish to 18x20"

[rmarkins]

I just bought an triple LNB 18x20 dish to replace my 2 LNB model, but I am having problems with the signal strength now. My old dish always was in the low 90's, but the best I can get on Sat 101 is 45 now. The other 2 satellites come in just fine in the 90s. I spent a long time trying to get a better alignment, but this is the best I can get. I don't have any other ideas on what the problem might be.

Any suggestions on how to improve Sat 101?

Make sure the mast is absolutely plumb. After that, try adjusting the tilt and elevation a tiny bit at a time. Are you using a standalone signal strength meter? That might be a good investment.

This is the official installation manual for 3lnb dishes, hope it helps.
