     Well, sort of. Sometimes signals will be coming on a skew path; i.e. EU 
coming in from over AF (15 degrees direct vs. 60 degrees from here - a 45 
degree difference). If you look at the half-power points on the beam pattern, 
rocking the beam will get you closer to the skewed path as well as a stronger 
signals in both directions.

     Also, DON'T underestimate the power of psychological help!
