Only flipped pol on ONE end. Nobody at the other end to flip. It does make a difference on that chain, but not overall. Meaning...
If chain 0 is enabled, signal is -80, I flip polarity then I get nothing unless I enable chain 1. Makes sense what you're saying about the alignment. I've tried going waaay up and waaaay down, thinking maybe where I'm at is just a strong lobe. No difference. If I go more than about 2 degrees off, the signal gets so low that it will never connect. Moving the dish slowly (or using the secur-align bolt) is the same.
