I am receiving the 119 signal through the 110 lbnf and 129 through the 119 lbnf. I have no signal from 110 at all. I have covered the 129 and 110 and tried to reaim but cannot get 119 at all. Is it possible that the dish or arm is bent out of alignment? Is doesn't appear to be. I have replaced both the lbnf head and receiver with no change at all.
