Exactly. I can spend more than 15 min tweaking and re-tweaking the LNBF trying to get both, the way I want it and the maximum signal. May have it on the first try, but the tinkering part of me want to try to get it better.
Also, sometimes you get it in your mind that the signal should be in a place where it isn't because you have misread or have inacurate markings on your dish.
Best thing a newbie can do is IGNORE elevation maks on dishes, IMO. Only scale I pay any attention to is the latitude scale on my motor brackets. I think that was a major help to me that I started with homebrew dishes and mounts in that there ARE no markings. I HAD to learn how to aim by SIGNAL, not by some marking that may or may not be right.
